I just went to a Sainsbury's Local and picked up a bar of chocolate advertised at £2.40. It scanned at £3.00 and there was another shelf with the same bar at the higher price so I went to the counter, explained that I was confused about the price and the woman behind the counter went to check.
While she was doing that a woman who looked like a manager came up to me and very rudely told me there was "no need to get like that". I wasn't like anything. I was not rude, unkind, nasty or anything. I was perfectly calm. I told her I wasn't "getting like anything" and was merely confused. I was also confused by her attitude. She was very argumentative told me that "we make mistakes" which I acknowledged but she continued arguing with me saying"I've just told you we make mistakes". I hadn't even complained, simply asked for the correct price. I told her she was protesting too much at this point.
She was really confrontational at which point I said "you know what, let's just leave it" and I left the shop. I'm actually shaking and I don't know why. Her reaction was out of all proportion. I feel quite sick.
