Only actually saw this for the first time last week so it's probably a new trend, but people who use a self-service check-out for a trolley-load of items. A bleedin' trolley .
I just want to understand the logic here, not only is a manned till going to get the job done quicker, it saves the shopper a huge amount of the work involved in scanning so many items, surely doesn't even fit on the weighing pad of a self-serve, and it takes up time and space that other shoppers could be using, the ones that are actually trying to just get a few quick items and go (unless of course
they I need to feed the machine some loose change ). If you're worried about an embarassing purchase do it seperately, and if you really insist on self-serving a trolley-load of items then do your shopping at 3am or something.
First time I saw this there were 2 offenders taking up half of the 4 stations available, the second there were 3 with bigger loads, luckily security started dealing with it so it clearly isn't some rules being relaxed on Tesco's part. Of course my brave fight against this weird trend involved waiting patiently in the queue and quietly tutting.
