I cannot risk 'Scan and Go'. I have mentioned this before but between my dyspraxia and ADHD, I have no confidence that I would remember to scan every item. In fact I can be very sure that I would not scan everything.
In principle I like the self-service tills, my main beef is that they are badly designed for the shopper to shop efficiently.
For exmple, if you are using your own bags and they are those floppy fold up ones, it is almost impossible to put the first few items in the bag without lifting it off the base to shake it out. it is meant to sit on the base and be touching it all the time.
This ends with goods being double handled once onto the scanned shopping surface and then into your bag. Even the very few supermarkets with self service tills designed to take a trolley load of goods, the same problem arises and all bags have to stay on the bought shop surface until everything has been scanned. There is also nowhere convenient to put the trolley while you unload or reload into the trolley to take to the car park.
Ths morning, we nipped into Waitrose to buy a magazine. DH scanned it..........and waited until he realised he hd to put it on the scanned goods shelf before he could pay, so he put it down, pad and then had t pick it up again. A minor thing, but so unnecessary.
