Self Scanners

Him indoors and I had to go shopping so we popped down to the local retail park in Bexhill so we could pick up some stuff for the little critters in Pets at Home and some new ink for my printer in PC World. Whilst there we popped into the Tesco's and got four items. The less than ten items checkout was closed so we thought we would use the self scanners . What a croc of pooh! Each item we scanned came up 'please wait for assistance!' What assistance does four pints of milk, a bag of sausages and two steamed meals need? It would of been easier to have gone to a normal checkout lol.
