Went to a textiles shop today and grabbed a few items and went on to do y other bits in town gt home to realise I was only charged 1.80 and the fabri scissors I bought were 4.99 themselves. It should have come to about £7 ad now I feel guilty for by realising at the time. Should I go back tomorro and let them no and pay the rest? I am just worried they may think I stole the items and have one back with a guilty conscience
