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
Even if I’m in a hurry, I splash them in water with a squirt of soap and quick scrub. I touch keyboards all day and my hands need to be cleaned. Never mind when I physically worked with IT equipment.
