Just been down to Tescos. I only had a few items so went through the self service checkouts. Three times I got, "unexpected item in the bagging area, please wait for an assistant"
. Now, this store has 31 checkouts, two of which were manned, then there were the six self-serve ones, manned by one poor love who was struggling around on bloody crutches!. Three times to me, one visit to somebody else, all in two mnutes, she'll have earned her crust today
