I finished work earlier today, and just got two phone calls from a colleague asking where something was. First time I politely said I didn't know and perhaps to ask colleague X.
Then she rang back to say colleague X had said I moved it and where was it, I said I didn't remember and pointed out it was a few hours ago now, colleague makes me look through my pockets and just kept saying 'well it is not there it it not there' I said to ring out boss and she said well what can they do so I said well what do you want me to do and she just kept repeating I had it last!
WIBU to have shouted at her in the end?
