Sometimes a person forgets to eat dinner, or sometimes they just didn't have time or money, and then they ended up at the bar and the only snacks available were Rainier tallboys. And yes, sure, sometimes they grab your beard and tell you, "You are drinking the most successful sausage," even though that's barely even English, and then they lose their keys and have to sleep on your floor, where they wake up utterly bewildered and have to walk all the way home and drink a Big Gulp of Sprite for breakfast on a Thursday. Be kind to these people. They mean well.
I have been known to spit the chocolate chips back into chocolate chip cookie dough ice cream. They're gross.
