Help

I can’t remember much of a manga, but one part that sticks out like crazy: Two salarymen are on a trip for work (I’m prett sure). They are awaiting the bus (I think), but one has to pee really badly and refuses to do so outside, so they go into a love hotel. The other accidentally traps the one who has to pee in a cage, so he has to pee in a towel. I can’t remember much beyond that, but it’s driving me bonkers trying to remember. Help, please!
