Congratulations! You're the one millionth customer of Honest John's Dealership! Or maybe you're the ten thousandth customer of the Malt Shop! Or maybe it's just an ordinary shop in an ordinary mall. Well, either way. YOU are the lucky person that's a milestone of their history—you are their hundredth/thousandth/millionth/billionth customer, and what better way to show their appreciation than to give you this random item?
Expect a shower of confetti and balloons when this occurs, almost as if it was a birthday party. Which it technically is, just for the company.
In reality, for the very very very VERY few places that actually do this, it'll simply be something small like a commemorative pen or badge. In media, however, this item (or series of items) will be something either extravagant or extremely desired—so, the conflict of the episode will sometimes either be resolved by or revolve around this item. Of course, sometimes it's not the item that drives the plot — it's the event itself, especially when its appearance can be a hindrance to the recipient.note
- Zig Zagged a bit in the MegaMan NT Warrior manga. There's a scene where Lan is told he's the one millionth customer of a restaurant, so he won a free helicopter ride as a prize. At this point, he and his friend Chaud are on the run from the government because of MegaMan's new powers, which they fear. Once Lan goes up in the helicopter, he reveals that he knows that this whole "millionth customer" was a sham, and that this is an attempt to kidnap him and draw MegaMan out, but he's willing to do it so that he'll see MegaMan again. Immediately turned around, as he really has won the trip and this is a genuine prize, and the pilot has no idea who Lan is.

- A Running Gag in Archie Comics seems to be that Jughead would always be this whether it's a restaurant or a grocery store.

In one story, during which Jughead suffers mishaps due to being in the wrong place at the wrong time, he and Archie enter a department store when erupts in cheers. Jug being the Umpteenth Customer wins a date with a beauty pageant winner, whereas Archie, as the customer after Jughead, wins one of the more expensive goods. Being a He-Man Woman Hater, Jughead isn't happy with this arrangement—and neither is Archie.

And then held hostage along with the manager and store detective by an armed robber. It eventually transpires that this was all a plot by the manager and detective to take the money, with Del, Rodney and Albert as independent witnesses, but went wrong because the robber's watch (bought from Del) was slow, so he missed the safe's time lock. After everything's been resolved with no harm done as long as the Trotters don't spill the beans, Del suggests to the manager that maybe they will turn out to be the millionth customers after all...
