Getting crazies just comes with the territory over at the service desk. It's like a magnet.
My personal favorite return was a gal that had an expired receipt with half the barcode ripped off the top, the bottom had the receipt and vcd numbers ripped off. She was trying to return a 120 dollar turn table. "Um mam, I'm sorry, but you don't have a valid receipt, yours is missing all the information we need to process this return and above all, it's expired. We could try a no receipt return, but you're only going to get the lowest selling price if the system allows us." "WELL THAT'S NOT RIGHT! I PAID 120 DOLLARS FOR IT, IT SAYS I DID RIGHT THERE, THAT'S A VALID RECIEPT!!" "I'm sorry mam, but no, it's not. It's expired, and you tore away all the information we need to even attempt to process the return....." "I WANT TO SPEAK TO A MANAGER!!" "Sure, thing mam..." Called the GSTL over, told her the same thing, she called an LOD over, same thing, she stormed out of our doors yelling she would never again shop at Target. At the end of the day she only made herself look like a complete ass. It's not our fault she didn't open the box to make sure it worked until 8 months after she bought the damn thing. Favorite part about it was the line of guests waiting behind her smiling and laughing with us. The very next guest I called up laughed and said: "My return will be simpler, here's my valid receipt, here's my item." I looked at him and just started laughing.
The craziest thing we had happen was when we had a bomb threat at our store delivered by a wacko claiming that our store was somehow in violation of some ordinance. I couldn't understand a thing he was talking about. Our store closed and was evacuated and the bomb squad searched our store that night. I later heard from one of our LOD's that he barricaded himself in his house and after a stand off was apprehended by the police. That was probably the craziest guest I ever dealt with.
