I was in Tesco about an hour ago - it was pretty busy but people all had masks on and were trying their best in the main to keep their distance ... as was I.
I don't really know what happened exactly, or why he did it, but I was picking up some fromage frais - nobody particularly close by - and I suddenly got shoved from behind. Turned my head to be presented with a alpha male type who lifted his arm (trying to explain that this was very much intentional and meant to hurt) and elbowed me in the back of the ribs with some real force. It was enough to wind me and cause me some real pain.
He walked off pretty briskly but squared up to me (from a distance) when I shouted after him "what the hell do do you think you're doing? You're an idiot!" (not my finest moment and probably very unwise but I was so shocked), although I think he thought better of it when he realised how many people were around. I was walking away by then, trying to calm myself down (had horrid heart palpitations - probably due to the adrenaline!) and just get away from the situation.
A couple of women (separately) caught up to me to see if I was ok/say they'd seen what happened/congratulate me on pulling him up on it - which was very kind, but I am still super tearful and shaken up. I'm a 42 yr old woman, FFS, really need to get a grip, have a glass of wine and forget about it.
