I thought #13 was hilarious, i can imagine how that conversation went:
Patron: WHAT THE HELL KIND OF BUMPER STICKER IS THIS? FUCK THIS! I WANT A COUPON GOD DAMN IT!
Employee: I'm sorry we don't have any coupons!
Patron: OH MY GOD I'M GONNA KILL YOU IF I DONT GET A FUCKIN' COUPON BITCH!
(Patron pulls out a gun and puts it to employee's head)
Employee: Here! Here take this coupon for a cheese burger!
Patron: THATS FUCKIN RIGHT BITCH.. AND SCREW YOU GUYS!
