THE TURN AROUND IN CIRCLES JUMP BACK STAB HAND SCARY CRAZY MAN

this guy comes in the store frequently. not as frequent as some of our daily customers, but he's a regular to the store. sometimes he has one or two other guys with him. one time he was all angry and was cussing the other guys out saying 'F' this and 'F' that. well, he comes into the store all alone. he buys his alcohol (his usual purchase), and goes to pay with his credit card. now, at least he pulls out his i.d. each time. i'll give him that. but when i go to hand him the receipt to sign, he grabs it off the counter (usually he'll just turn it in circles three times and then sign it), and wrinkles it as he holds it to his chest. then, he grabs the pen and stabs himself with it where the receipt is. then, he holds it (the receipt) with one hand while he signs it with the other. he then remembers that he also wants some cigarettes, and so i go to get those for him. this time he doesn't stab himself, but he still grabs the receipt and holds it to his chest before holding it in his one hand to sign. then, as he leaves, he grabs his bag and 12 pk and forgets his i.d. and credit card, so as much as i want him to just leave, i have to call him back to get his cards and after he gets them, as he's walking out the door, he turns around in circles and jumps backwards out of the store. boy was i sure glad he was gone.
