The “leader” of the group was a bit of an idiot and let me go after I’d said that I didn’t have a bottle and showed him my receipt. I carried on but the mob returned, this time with a suited man who told me again of what I’d apparently done. He then searched me but, of course, he couldn’t find a bottle. He looked a bit confused, as if I’d just performed a magic trick to make the bottle disappear in front of him. There was a bit of a mumbled apology before they returned to the shop.
I’d have liked to have seen the CCTV images of “me” taking the bottle. Nowadays they have security men that would have stopped me as I left.
