it wasn't what is was over, it was the fact i told him several times i hadn't and he kept accusing me, essentially calling me a liar. the guy is a tit, never says a word to me usually, refused to train me when i started in the job, will even walk off when trying to strike up conversation, probably use his ethnicity as an excuse for these things but fine with others.
As i say i wasn't fuming at the spark of it, just of accusing me of something that i hadn't done so vocally, even after it was proven i could not have done it.
But not the first time this has happened, think it would be massively unprofessional if it doesn't get acted upon considering it happens again and again
