Multiple times that I ve been here I order a large shakes and get charged for larges but handed mediums. First time I figured It was just a slip up but it seems to be a common theme here.. especially since they don t give you a receipt so they think you won t catch it. This time they were right I had already got home before I realized what had happen, jokes on me for talking with my passenger I guess, I should've made sure that I got what I ordered.
