I'm worried because I let my step dad use my sainsburys discount card and he's not the named person on there. He was buying stuff for the household and whenever my mum and step dad drop me off I always give them the card so my mum can buy the shopping and I just wasn't thinking so I gave it to him and he probably saved like £5-6 max but they monitor the card and who uses it. Has this happened to anyone? Did they call you into the managers office or anything? I'm getting really paranoid and wondering if I should just mention it to a supervisor because they're really strict about discount card use.
What should I do?
