How Much?

I went to lunch with the Contractor today to talk business. We ended up going to Kelly's Tavern. It was a fun time, but I didn't think of the bill till I got back to the office. It was $15 for the daily hamburger special. So I got a hamburger and a coke for $15? The waitress wasn't topless their was no happy ending? Jeez I got to ask what the special cost next time.
