Dear 100 Hour Board,
Those people who use the toilet seat liners, and use toilet paper to touch handles and doors, how do they fasten their pants and buckle their belts before getting to the sink?
You use one hand to grab everything and the other exclusively for doing up your pants. It may take some practice, but doing up pants one-handed, or setting up toilet seat liners one-handed is totally feasible.
Barring that, hand sanitizer and wipes are very useful when it comes to cleaning things like buckles, buttons, and zippers.
