Do your teeth rest?

I don't normally frequent Starbucks, especially with two kids nipping at my heels, but today we stopped in for a small treat while we were getting the car washed. I have always thought that the people who sit in Starbucks look so relaxed drinking their iced-mocha whatevers, typing away on their laptops. Today I wanted to join them in their relaxation but I just couldn't. See the man sitting one table away from us was sitting at his table drinking his Venti something or other...but the thing is, he had a plastic Starbucks cup filled with water on the table....it had his teeth in it. Nothing says relaxation like letting your teeth have a rest.
