A man rushed into a bar and ordered Double Bottles of Hero. The man downed it with one swallow and gave the bartender #500 and turned and rushed out of the bar. The bartender picked up the #500, and folded it carefully and tucked it in his vest pocket.
Just at that moment he looked up at the boss standing in the doorway staring at him. Doing a bit of fast thinking he said, “Hi boss, did you see that fellow just now? Came in here, bought Two Bottles of Hero gave me #500 tip and rushed out without paying.”
