First off I'm not sure if this is the right area for this so mods can feel free to move it.
Anyone working retail ever delt with someone that you know is chancing their arm?
This guy came into us with a Music CD claiming he bought it here and it was faulty and wanted a cash refund. The funny part is it had a sale sticker on it from another company

He tried to argue he bought it here but I kept pointing to the sticker on it.
Another time someone wanted a cash refund on something our company didn't even stock

.
Anyone else got any stories?
