Treated like dirt and called a liar
I took some coupons that my wife printed out to purchase some YoCrunch Yopa yogurt cups. The coupons wouldn't scan and instead of keying them in, the attendant asked the manager in the customer service desk for help. The manager claimed that the coupons were copied and continued to argue that fact with me after I assured her that they were not. She called me a liar and talked down to me the entire time. I have NEVER been treated so poorly at a grocery store before in my life. The only reason I gave it a star is because it wasn't mugged on the way out.
