The supermarkets here are too stingy to be helpful, but when I lived in portugal they had an excellent scheme in the supermarkets there.
You had a locker which you put all your bags and even coats etc into and locked it with the key, which had the number and a tab on it. Then you were free to walk round the store unencombered and of course from the stores point of view , no bags to let you shoplift. You got your items and then usually as you stood in the queue to pay at the checkout, walked across and retrieved your possessions and bags so that when it was your turn, he presto bags at the ready, no embarrasing monent when you realize you had put that toothbrush or soap in your bag not the supermarket one. Easier on customer, staff , and security. cost was space for the locker rack. this lot only see it as another space to sell something else. This would help in many ways.
I did hospital car for 3 days a week for 10 years and you may be sure i saw all sorts of goings on with wheelchairs, properties etc. if you were there with someone else not so bad , but being in a waiting room alone, if y ou need the loo or are called to the desk you have to gather up everything and try to be in a hurry (which with my back, is difficult!) I think that again if there were space for a locker idea, it would be so much easier to park your outdoor coat or jumper and bits in, as inevitably the hospital is roasting hot in the waiting rooms and it is freezing cold outside. They could have them by the doors as you came into the hospital so again you walk easily round the hospital with only the things you need. Ah well common sense is always bypassed when they see a way to charge you for something.
