I work in a chain supermarket, but in quite a small store (30 of us work there, some just weekend staff, some morning and some evenings - but we all know each other.)
One girl (think shes about 19/20) only works at the weekends. I finished work last weekend and did my shopping, I was having a movie night and did end up buying a lot of snacks (£20ish worth)
Anyway I paid for it and went home. Came into work today and a colleague told me that the girl had taken a photo on her phone of my receipt (just of the items bought) and she had overheard her laughing and joking about it with another girl at work (roughly the same age) - the girl who didn't take the photo was daring her to put it on facebook and tag me in it (she obviously didn't though)
I am a large woman but aibu to be upset by this?
