Though it sounds understated, it can mark the beginning of a change in a character or relationship.
Alice has always disliked Bob or people in general or is just very proud. But to Alice's dismay, she gets helped out by Bob in a moment when she really needs it. Glumly, Alice accepts and just when Bob is leaving Alice goes:
"Oh, and Bob..." Then a pause to indicate Alice biting the bullet. "Thank you."
Compare Think Nothing of It and Does Not Know How to Say "Thanks". If Bob has the same attitude as Alice, he is prone to express it, either because he dislikes the connection it formed, or because he did not act for Alice personally. Sometimes another character may apply a Prompting Nudge to get Alice to express her gratitude.
- After Zatch saves Kiyo a few times in early Zatch Bell! episodes, Kiyo tries his best to thank him but can't get the words out, settling for "I owe you". This is played more dramatically in the manga.
- Seto Kaiba from Yu-Gi-Oh!, who wasn't happy about losing his World Champion's title to a virtually unknown kid, grudgingly thanks Yugi for saving his little brother Mokuba at the end of the Duelist Kingdom arc.

- After taking a literal beating from their father covering for his little sister's hobby, Kousaka Kyosuke goes about his next day like any other. This trope was major character development for Kirino, including the first and so far only time she addresses him as brother and led to Kyosuke proclaiming "My little sister can't be this cute."
- The Quintessential Quintuplets: At the end of the Fireworks Festival arc, Nino doesn't quite say the words to Fuutarou, but her "Good. Job. Back. There." after he does his best to reunite her and her sisters definitely carries the intent of this trope.
- King Faraday delivers one (via telegram) to Batman in Batman #314 after Batman saved his life against Two-Face. Batman notes that a 'thank you' from someone like Faraday is glowing praise.
- In Transmetropolitan, after Spider Jerusalem gets knocked out during a severe storm, his assistant Yelena Rossini proceeds to write a critical story in his name to make a deadline.

- Doctor Doom, of all people, in Doctor Strange and Doctor Doom: Triumph and Torment, thanks Strange for protecting his mother's soul from the wrath of Mephisto. It's pretty much the only hint of gratitude Strange gets during that misadventure, though.

- In the Rango fanfic Old West, the second meeting between Rattlesnake Jake and Grace Glossy happens with her farm being attacked by rustlers and him showing up to deal with them.

- Corrupt Corporate Executive Zorg in The Fifth Element sort-of gives one of these to Priest Vito Cornelius after Cornelius saves him from choking on a maraschino cherry. "You saved my life. And in return I'll spare yours," and lets Cornelius leave... escorted out by his bodyguards.
- In Predator After the character Mac saves Dillon from a scorpion crawling on his back by pinning it on his knife, Dillon pauses and resentfully says "Thanks".
- Played both ways in Logan. Wolverine is only reluctantly convinced to take Laura on a road trip to safety. But halfway through the movie, Wolverine thanks her for taking him to a doctor after he passed out. Laura replies, "De nada." ("You're welcome.") This causes a WTF reaction in Wolverine who up to now had no idea that she could speak. Laura responds with a Foreign-Language Tirade that those who speak Spanish will understand is a What the Hell, Hero? to Wolverine for his own attitude.
- Artemis Fowl to Holly at the end of book two.

When a vornskr does finally get past her defenses and goes for her, Luke takes back his lightsaber and saves her with considerable difficulty. She has him drop the lightsaber and back off before very grudgingly thanking him and saying that now they're even for when she did not kill him immediately after finding him. But she still hates him.
- In Isaac Asimov's The Robots of Dawn, Elijah Baley receives one of these from the Chairman of Aurora, after the Chairman was prompted. The Chairman rarely thanks anyone; thanking an Earthman was... impressive.

- Turn Coat: Morgan starts to give one of these to Harry. He cuts Morgan off, stating that neither of them wants to hear him say that, for which Morgan is more than agreeable with.

- In the Tom Clancy novel Patriot Games, ULA terrorist Sean Grady is temporarily transferred to a cell with ordinary criminals in it. When the cops check on him, he's been beaten and is being raped. The officer pulls the other prisoner off of Grady and gets him to the infirmary, at which point Sean says "Thanks." This is notable in that it's literally the only unnecessary word that Sean says in the presence of the police between the time he's arrested and the time he's broken out (At which point he shoots and nearly kills the officer who saved him).

Spock: Doctor, I am seeking a means of escape. Will you please be brief?
McCoy: What I'm trying to say is, you saved my life in the arena.
Spock: Yes, that's quite true.
McCoy: [Indignant] I'm trying to thank you, you pointed-eared hobgoblin!
Spock: Oh yes, you humans have that emotional need to express gratitude. "You're welcome", I believe is the correct response.
- There's another one in "Let This Be Your Last Battlefield". One of the aliens of the week is set up as someone who's hotheaded and difficult but ultimately at least somewhat sympathetic. Viewers get a hint of that second half coming when in his first exchange with Kirk and McCoy, after reacting very angrily to their (perfectly accurate) accusation that he had stolen a Federation ship, the alien visibly pulled himself together enough to thank them quite sincerely for rescuing him.
- In the episode "Bread and Circuses" Bones gives Spock a Grudging "Thank You" and receives a Think Nothing of It in return.

- This happens in Misfits when Nathan gets rescued from a totally ridiculous situation by Kelly. He doesn't actually utter the words "thank you", but he mumbles and gestures awkwardly until Kelly asks if he's trying to thank her, and he admits: "I guess I am". Cue awkward silence rife with UST.
- A subversion occurs That '70s Show when Red "thanks" his son Eric for staying at home to help support the family instead of going to college after Red had a heart attack and couldn't work for a while. He expresses it by ordering Eric to go out and mow the lawn, awkwardly adding that the "lawn...thanks you for staying home." Red legitimately appreciates Eric's helping to pay the bills, but he's just extremely uncomfortable expressing his emotions except for when he's angry.
- Super Robot Wars: Original Generation Gaiden had this after Axel had saved Lamia, even though he was formerly an adversary (but got a HeelFace Turn). And then the next time they meet, they help out each other and just before Axel could leave, Lamia stopped him with
Lamia: Before you leave, can I say something, Captain?Axel: Sure. Go ahead.Lamia: ... Thank you.

- In The Last of Us, Joel scolds Ellie for breaking the normal plan of regrouping despite the fact she saved him from a Hunter that was drowning him, making it necessary in the first place. Later when he finds her a rifle to help him shoot some Hunters outside before going off he says "And for the record, it was either him or me." to which Ellie responds "You're welcome." after he jumps down outside of hearing distance.
- In Overwatch, one of the commands the player can input is having their character say "Thanks." Reaper's sounds like he'd really rather not admit he needed the help.
- Resident Evil 5: in the "Mercenaries" mode, Wesker's most common response to someone helping him is "I suppose I should thank you," said in the most disdainful way possible. Although in "The Mercenaries 3D", he says "Thanks for the help" in a slightly more sincere way.
- In the end of Bug Fables, during the final ceremony, when Team Snakemouth talks to Mothiva and thanks her for helping them in the Giant's Lair, she accepts the gratitude in her usual way, and then thanks them back, but the variety of faces she makes before thanking clearly indicates she does that really begrudgingly.
