I’m brushing my teeth and having so much fun, I never let the water run
I’ve only ever seen 1 guy ever do it at work. I don’t think he was American.
I’ll admit, I have a toothbrush and toothpaste at work. I’ll also admit that I’ve never used it. It’s there in case I know I have some bad breath and need to take care of it.
Logically, it shouldn’t be weird. It should be standard health protocol to brush after lunch.
Some might get all germy scared about the public bathroom situation, and I’d get it, if it didn’t get cleaned once a day.
