Does anyone else find it odd that WDW guests are willing to repeatedly reuse a mug that hasn't been sanitized? I mean guests would never knowingly allow a CM to serve them from a cup that wasn't sanitized, yet they will self-serve from the same mugs for an entire week. Surely many families end up switching them around among family members. Surely many folks refill a mug that has a sugary residue and was in 90 degree heat all day. It makes me wonder if anyone ever gets sick from using one. Does anyone do anything special to sanitize their mugs? When I use one, I'll use some of the in-room shampoo (like dish soap?) to wash them in hot water each day. Maybe someone has a better suggestion. Or am I just being paranoid?
