I usually go to the Charlies at the Beaver Valley Mall, but yesterday I was out at Robinson Mall and decided to use my stamped Charlies "buy 7, get 8th free small sub card" I had been saving. When I ordered and handed the cashier (and manager apparently) "Angel V" my card, he asked where I got it from. I said the Beaver Mall, why? He said I could not use it, and could not have it back! He said the numbers stamped on the card were different than his stores numbers. because it's a different location (different stamp) obviously! So I couldn't use it which makes no sense. I still don't understand. I argued it was my property and to give it back so I could use it at the Beaver Mall then and get my free sub. He refused to give me it, tried ignoring me, then embarrassing me in front of other customers and then said he was calling security. I did nothing wrong. I was outraged! I told him I'd call his boss, and I have, but no answer back. It is not right how he treated me, and I will happily never go there again! Worst Charley's ever.
