Bobby walks into a bar and says, "Bartender, one round for everyone, on me!"
The bartender says, "Well, seems you're in a really good mood tonight, hmm?"
Bobby says, "Oh, you can bet on it! I just got hired by the city to go around and remove all the money from parking meters. I start on Monday!"
The bartender congratulates him and proceeds to pour the round.
Monday evening arrives and Bobby comes back into the bar and says, "Bartender, TWO rounds for everyone, on me!"
The bartender says, "Well now! If you're so happy just over having this new job, I can just imagine how happy you'll be when you get your paycheck!"
Bobby looks at the bartender with a wondrous look on his face, pulls out a handful of quarters from his pocket, and says, "You mean they'll PAY me too?"
