imagine someone starting a "wet taxi" service. at first, they bill it as a service for messy drunks in the downtown area, who might not be able to control certain bodily functions until they get home. this service anticipates that, and boasts a cab with a "quick clean" design... all the inner parts are removable/washable, and the cars return to their dispatch center after every trip, so the cab can be refreshed.
of course, this becomes a favorite ride for anyone who wants to pee in the car. some people will at least get drunk beforehand so they have an excuse, and some drunks have genuine pee accidents on the seats. but some will just get in the cab, already full and fidgeting, and the driver immediately understands why they chose their service over a normal cab company. an "accident" soon follows, and there have been a lot of very cute little shy wettings in that seat... this cab driver has seen it all. but what happens in the cab, stays in the cab. some people will just get in and piss themselves like it doesn't even matter, or will straight up use the taxi like it's a toilet on wheels... just pulling down their pants/underwear and pissing on the floor with no shame. one time a whole huge group of frat boys piled in, only riding for 5 minutes to get to another bar, but on the way they all pulled their dicks out and peed on the floor, to the point where pee splashed out onto the pavement when they opened the door at the end, and several guys got their adidas sandals drenched.
sometimes a group will call a wet taxi, and most of them are fine, but they have one friend who's kind of red faced and teary, and the conversation makes it clear that this one person doesn't think they can hold it til they get home. and about 3/4 of the way through the drive, they're proven right... that person begins to pee their pants, and their friends all seem super sympathetic, saying it's okay, that's why they called this taxi, yaknow? maybe someone in the group tries to wet in solidarity, and though they can't let out much because they didn't have to go... they peed themselves enough, and it's the thought that counts.
of course, with all that peeing going on in the back, the cab driver might find themselves a little desperate sometimes too... maybe in the early days of this service, the driver's seat was normally upholstered, but then after a couple of driver accidents, the company realized the need for quick clean driver seats too. just imagine the first driver to pee their pants because the passengers made them too desperate... the sinking feeling as they begin to soak themselves, and then having to go back to the dispatch, and explain their own puddle and wet pants.
Ohhhh, what a clever idea! Can't hold it for the whole journey? Get a wet taxi and just let it out to your heart's content! Good for drunks, certainly, but there's plenty of other types of people who could appreciate such a service... And yes, the driver's seat not being waterproof too is a bit of an oversight! I'm sure the company will fix THAT quick... XD
