"How was your day?"
"Well, let's see. I lost $100 while at work today. While I was trying to figure out who might've taken it, one of my tables walked out on me on a $200 check. Then I got sat a party of 8, two minutes before closing...and it was their birthday...and they only left me a $2 tip. I then had the salad bar all to myself as my sidework. If this wasn't bad enough, later that night my girlfriend's mom walked in on us while having sex in the livingroom. I got out of there as fast as I could, but I didn't see my car in the parking lot. You want to know why? It got towed."
"Damn dude, sounds like an Alan day"
