I don't have too many problems with the logistics, but I'm a little squeamish about germs. I'm lucky enough to have a single-stall restroom that's used mainly by me and a few coworkers, so it's not super gross or public. But the water isn't as hot as I'd like and I worry about having germs on my hands when I handle the cup, or there being germs on the toilet paper that I use to wipe the cup with.
I've read plenty of advice on how to clean a cup in public. I'm just nervous about germs or the possibility of getting a UTI or something. I was hoping people might have tips or reassurances.
