rude Manager

i left my parking ticket in the change rooms,15 minutes later I retuned and asked the gentleman looking after the change rooms if he had seen my ticket, he said yes he saw it just outside the entrance to the rooms, but it was no longer there. he said guess someone took it and he walked away from me. I went to the security at the door who helped me look and I asked her to call the store manager for me. A lady by the name of Rosa came who is the store manager, I asked her the same question about the ticker, she then attacked me and proceeded to tell me that a parking ticket is just a piece of paper and of course they would throw it away. she further more said a parking ticket is not a belonging. I told her it is a belonging just like car keys that a customer would need to leave the centre. She then told me I was being rude about asking for my ticket. this also shocked other customers who were standing near us who even said \we know this shop they have a bad attitude they never want to help"As a store how do you have such rude"
