I bought a few items from M & S Food Hall just as they were closing - the total came to £13.05 and I gave the assistant a £20 note. She asked me if I had the odd 5p - I checked and found that I only had 10p so I gave that to her. She gave me back a £5 note, ONE £1 coin and ONE 5p coin. She did not count the change back to me, but instead she just dumped it in my hand with the receipt and turned to the next customer.
I am not a naturally suspicious person, but this just didn't feel right - so after a quick bit of mental arithmetic I kept the change in my hand and called the assistant back and said "This isn't the right change". Immediately she said "Oh - did I give you £1 short?" Now I hadn't mentioned that the discrepancy was £1, yet she immediately knew what was wrong. Can't have been a mistake can it?
Am I being unreasonable to expect Marks and Spencer staff to be better than that?
What is a reasonable minimum spend for an online grocery delivery??
