Back on topic, I also like meeting new folks when camping and a quick wave is fine when someone has dirty hands!
(I, also, use an old pair of rubber gloves for my sewer hoses and store it all in big plastic bin and the gloves are on the top of everything...I keep a container of baby wipes in the truck door that I use to clean up afterwards.)
Two types of people I love messing with...OCD'ers and germophobes...just too easy!
