Some people can't "do their business" when there is a chance they could be seen or overheard by someone else. This is somewhat understandable and a case of Truth in Television for some people. This can vary from not wanting to be watched (which most of us can say we'd agree with) to not being able to use public conveniences even if they are the only one there.
In fiction this seems to be an affliction that tends to affect shy and/or neurotic people more than anyone else. It also seems to be something that tends to affect children. A common cry of such a character is "I can't go with you looking at me!" (or "with you there" if the person is merely in earshot).
A Shy Bladder may be faked if a person needs to evade observation for some reason or if they want to avoid giving a urine sample as, at least in fiction, even prison guards will sympathize with a person over this.

- In Trick, Gabriel is trying to pee in the bathroom at a gay club. But a drag queen with a vendetta barges in and starts telling him a long story about Mark, the go-go dancer Gabe is trying to land. During this Gabriel is increasingly nervous and can't pee (he asks her to turn around and she says, "Pee shy? Don't worry, Miss Coco's here to help." — she turns around, then turns right back for the next salvo). Finally the drag queen delivers the final, climactic invective against Mark, and, in a bit of auditory punctuation, Gabriel is suddenly able to pee ("Good boy!").
- Still Game has this happen in the first Hogmanay special "The Party" when Winston, Jack, Victor, and Isa are all stuck in an elevator.

His soon does give way to it though.

- In Diary of a Wimpy Kid: The Long Haul, Greg and his impromptu pet pig (long story) both need to use the bathroom. Greg says "It was pretty awkward using the toilet with a farm animal sitting next to me, but I guess the pig was more embarrassed than ME, because when it was his turn to go, nothing happened."
- In The World of Poo, Plain Old Humphrey explains to Geoffrey that having a young boy standing outside the privy waiting for you is not conductive to your business, even if you can't see him. (The fact Geoffrey has just explained his idea for a poo collection, and is waiting with a bucket certainly didn't help.)
- "I Piss Alone" by Regurgitator is about this. "I piss alone, 'cause I don't want nobody to know/that I haven't got the pressure of some of the other boys/they make a noise that scares me so".

- Some Japanese women are very self-conscious of the noise they make during urination, so much so that there is a device called the Otohime which makes flushing noises when it is activated. It was invented to conserve water, since women would usually cover the noise with actual (and unnecessary) flushes.
- It's commonly accepted (well, in America, at least) that if you, a male, go into a bathroom and it's empty, you take the urinal farthest from the door or the stall. If another person comes in while you're still using the urinal, they take the one farthest from you or at least take a urinal that leaves a urinal between you. Talking or touching is not accepted, even if you're drunk.
- Sometimes lineups will form for urinals even when there is one (or more) free. This is how strong the unspoken rule about taking a urinal adjacent to one in use is.
- Occasionally, to counteract this, small mini-walls are installed between urinals, just so men will use them all, rather than every other one.
- No talking, stare directly ahead.
