circle k Circle K and thier constant negative upselling tactics like always asking people for thier change chandler Arizona

Circle k has been known to constantly up sell their customers. So today I found it quite fulfulling when a customer who was right in front of me inline blew up at the clerk when she asked the customer if he wanted to donate his change and he quite clearly informed the clerk that she makes people people feel "real guilty" when they do that and then stormed off. After this exchange that took place and after that customer left the store unhappily I then asked her why they do that? and she claimed that it was circle  k's policy that they must upsell and ask every customer for their change, and that she would get in trouble if she didn't ask.  Well then this is just terrible customer service if circle k does this, and it's no wonder why everyone is flocking to QT for their convenience store needs, and I totally let the clerk know that I agreed with the sentiment of the customer who was in front of me, because I have long felt that coming to one of their stores has always made me feel this way, and this is the exact same reason why I don't go to circle k unless I absolutely have too. Circle K go ahead and keep up the good work!
