Bathrooms, public and private. As I blogged the other day, after I walked into a bathroom with no toiletpaper:
Is it really that hard to figure out what the outcome's going to be for the next person?"
What is it that keeps people from walking up to the counterperson at a cafe and saying, "Hey, man, you're out of toiletpaper?"
That's just one of my experiences. I'm sure you have plenty more. Lay 'em on me -- and please wipe the seat when you're done.
