You're probably wondering what I was doing in the bathroom of the grocery store. No....it wasn't an emergency. (Although, that has, indeed, happened to me in the past.) Rather, Michigan is a state where you have to return your cans/bottles back to where you bought them for $0.10/a piece. Unfortunately, most folks don't really "drain" their soda cans/beer cans/beer bottles before they put them in the bin. They leave a little bit of liquid in the bottom, so when they end up in our bags to bring back to the store, the whole thing is a big mess. After putting the cans into the machine, I use the bathroom to wash my hands.
As a side note...make sure you shake out your cans/bottles in the sink, please. So those of us who have to return them don't have to deal with the mess!
