Today I popped in the supermarket for cat food on my way back from a kids party. Went to the self service check out and paid but it was declined because I had the wrong bank card on me with zero balance. I tried cancelling the shopping but it needed authorisation from staff but they were really busy and were taking forever to come and swipe it off. Dd was restless and tired so I just left the shop but when I got home realised I'd put a pack of pampers under the pushchair and completely forgot. So now I'm worried the store are going to think I purposely left the store without paying.
What do I do? If i go back to the store will they call the police for shoplifting?
