My roommate only washes up if he poops, never after peeing. Now every time I’m in any of the common areas I have to wash my hands after touching anything I haven’t wiped down. Thus, I wash my hands twice every time I use the bathroom; once as normal and again in the kitchen because I touched the taps, light switch and door handle in the bathroom which likely have groin sweat on them… /rant
carry hand sanitizer, but also if it’s the washroom use paper towels to open the door, and toss it on the floor beside the door if they’re stupid enough to not keep a trash can there / within reach.
I avoid certain restaurants/cafes that don’t hove paper towel in their bathrooms for this exact reason. ;-;
