Glass bottles then cans, cartons of fruit juice, root vegetables, packaged meats, breads, vegetables, soft fruits, eggs.
You will have got there by now; it's the order you load up the conveyor belt in the supermarket. Well, okay, it's the order that I load up the conveyor belt in the supermarket. It's not OCD at all, well not in my book - it's just a sensible way to pack my shopping without the heavy items crushing and damaging the lighter goods.
It's a system that works for me and I am sure it works for you too. (Come on, admit it, you do it too.)
So, the other day in Waitrose, I was stumped and confounded to be confronted by the lady on the check-out with a system of her own. I didn't notice it at first - but began to realise that something was up when the goods coming down the slope towards me were coming at a slower rate than normal. I noticed that she was selecting items from the upstream end of the conveyor in a very particular way.
Apples, bottles, breads, butter, cans, carrots; it went on, with no apparent rhyme nor reason to the order of selection.
It was causing havoc with my packing regime at the downstream end.
It was only when I got home that I realised what her system was - it was selected alphabetically!
