A few times I've selected some fruit and vegetables from the shelf and had them bagged and priced. Then as I walk around the supermarket I notice the 2 tomatoes cost 21QR (so I left them in the chocolate aisle) the brocolli was going to set me back 35QR (so it was left in the toiletries aisle) and a sliver of pumpkin was priced at about 27QR (so I left it in the freezer cabinet).

I left with a litre of milk and an untouched shopping list.
