Ms M is an old hand at GoodGym shopping missions and had everything arranged beforehand. I rang her before setting off from home and she gave me a very detailed list. I ran up to Waitrose at the Brunswick Centre (Ms M's supermarket of choice) and managed to get everything on her list, with just one phone call to check where the low-calorie fish pie could be found. After paying for the shopping I rang Ms M to let her know the total, and she had a cheque ready and waiting to be posted to GoodGym HQ when I arrived. I carried the bags through to the kitchen for her and then took the cheque to the postbox. Very efficient! And hopefully Ms M will enjoy that fish pie.
