7-Eleven

I just left there a few minutes ago and the man at the register overcharged me. He double scanned one of my items. Initially I thought maybe it didn't scan correctly when he first scanned it, I saw that he scanned it again and checked on his screen but giving him the benefit of the doubt, there was a long line behind me and I didn't want to hold anybody up so I asked for a receipt and left. I know he did this on purpose because he didn't give me a receipt until I asked him for one and then rushed to tend to the next customer. I won't be shopping here anymore and I also see in other reviews that this is not the first time.
