Did you ever get a prostitute? If you ever hosted a house party in college, you know that it was only a matter of time until some random freshman would show up, get way too drunk, and then puke their guts out into the toilet before passing out on the bathroom floor. It was basically a rite of passage for everyone involved. If you've ever had to deal with an unexpected guest like this, then you're probably familiar with how indignant they tended to get when you told them they had to leave- even though they were never invited in the first place. Unfortunately, drunk people aren't easily reasoned with.
