It's 5PM on a Wednesday. I need to do the laundry because I have a client meeting tomorrow and they usually look at me funny when I wear crumpled tee shirts that smell kinda funky. I could do one of two things:
1. Work for an hour, generating $100, and spend 20% of that getting someone else to do my laundry. (Plus, I get to drink beer when I'm working at my desk, and I don't get to drink beer at the laundromat.)
2. Do the laundry.
