"Please put the items in the bag"
Why does that phrase create such a "road rage" like temper in me?
I have put the sodding items in the bag you daft machine, if you would just give me slightly more than 1ms to move them from the scanner to the bag.
In my experience... Morrison's are the worst - the daughter and I have a deal of fun breaking the machines in new and interesting ways. Once they upgraded the software and the daft machines stopped the incessant chant, however the next update restored the lost "functionality"
Waitrose have two systems - one where you do the whole checkout think yourself (Godalming is one store with that) and the other where you scan everything then take it to a till where a person handles the payment. Hardly ever have a problem with the Waitrose machines and only been checked about 3 times ever.
B&Q - I never have a problem with and their hand scanners are the easiest to use.
Ikea - meh - about average I guess. I will try them out tomorrow.
Tesco/Asda equally likely to utter the eldritch ire inducing words... but usually quicker than queuing behind someone who insists that 112 items are fewer than 10 in the express lane.
