Well. it happened to me - ended up getting reported for my ‘attitude’. Luckily, my manager was supportive. We also had CCTV…

Was working in an outdoor goods store. One summer we had a display of Gazebos & accessories. A woman, accompanied by her kids, came up to the till with a £100 gazebo. Put it through the till. asked her if she was paying by cash or card.

‘That’ll be £100, please’

‘No’, she says, it’s £10, not £100′. I explained that it was indeed £100, the £10 item was next door on the shelving. I looked, & sure enough the labels had been switched.

‘I work for Trading Standards, you MUST sell it to me for £10’.

I politely declined, & she stormed out. Reported me to Head Office. As above, my boss was supportive. We checked the CCTV. Clearly showed her standing in front of the display, blocking the line of sight from the till, while her kids swapped the shelf tickets.

Karen did indeed work for TS, & talking to other shop staff on the park this was her regular modus operandi.
