Tesco Privilege Card misuse

[SullivJ]

So I recently received my colleague discount card and today I went to do some shopping with two sister in laws. We are spending time at each other's houses this week because our mother in law is terminally ill and in the final stages of life. We separated the shopping in to 3 transactions for each home and I used my discount card on each shop (£50, £30 and £55). I will be using food in each shop but we paid for one each. Now I'm worried sick this will flag up as misuse and I will be suspended. I didn't even think until after the cashier told me to be careful. I would happily give back the discount applied on two of the shops if I have broken the rules. I don't know what to do other than wait and see. It's just another stress I really don't need. Am I being paranoid or am I likely to be called for a meeting? Please help!
