At the end of last year Henley Waitrose was refurbished, and the row of check-outs for ‘one basket only’ was redesigned.
Whoever did the redesign apparently didn’t give it much thought. There are five tills. You queue on the left and move away to the right. You would expect to place your basket on the surface to the left of the till so that the cashier (‘partner’) can unpack it and place the items on the right. But the space to the left of the till isn’t big enough for the basket. So you have to put your basket on the right, which is inconvenient and potentially leads to a muddle between items which have been rung-up on the till and those which haven’t.
If there isn’t enough room in that part of the store, then why have five tills? I have never seen all five open, even at busy times. The ‘partners’ are very efficient and one rarely has to wait very long in any case.
Four tills and more space would be my answer.
