Don't Come Back Customers Suck

I work at a super center, I had a customer come in and ask for a walkman to play his cassettes. When I told him that we don't sell them anymore he began to rage saying things like "A super store doesn't sell a hot item like that, what kind of people are you, I have cassettes that I need to play while I jog!" (he was like 300 pound last time he ran walkman was the thing.)
