Just been to boots with my dh and baby. Had 4 items to purchase, dh put them all on the little cash desk/counter and was looking at some toothbrushes on a stand next to us. I was holding baby so juggling baby and getting my card out of my bag and talking to the cashier. Anyway paid on contactless not really paying attention to how much it came to and at that point dh turned back to us, put the items in the baby bag and we left.
We have just got home and I've realised on the receipt she has only charged us for 2 out of 4 items! So we should have paid £14 and we paid £4 😳
Obviously this was an accident but I'm a bit mortified in case they think we did it on purpose or something! We are a small town and I go to that boots a lot so I don't want my name blacklisted so to speak!
I want to ring and explain but dh says that's overkill and I should just leave it as clearly it was an accident. AIBU if I ring? I'm happy to pay next time we are in (can't go back now as dh is going away for work conference and taking the car).
