In the interest of balance…
I'd ban customers so gormless that they have no:
– idea what they want, pick up things and abandon them randomly in totally unconnected displays. Want a yoghurt? Oh, there's one between the screwdriver sets and plastic garden clogs!
– respect for the staff's display work. Plastic garden clogs? They were easy to search for your size until made a chaos emulating that among the T-shirts. Oh – that pair I espy all lonely on the loo roll stack might be my size.
– ability to understand the photograph and text on the carton, so when you arrive home and think where to install that shiny wall-lamp you realise one such type has already opened the box and lost the crucial little mounting-bracket, so has closed the box and put it back. Hopefully in the original basket, not among the yoghurts or clogs.
.
The last happened to me. I took the receipt and lamp back, and suggested I search under the baskets. Sure enough, there was the lost part, huddled together with waifs and strays from other goods.
A staff member (sorry, 'colleague' ) in Aldi or Lidl told me it can take over an hour after closing to replace all the displaced goods and tidy the messed-up displays.
