This should be so easy for the stores to produce.
They must have the info to hand.
My local Tesco have introduced a one way system which works very well, but it would be brilliant to be able to write your shopping list in a better lane order.
I have a reasonable grasp of my local shop so know that it's veg > meat > dairy > ambient but I never can remember where the butter is.
Google found me this image which is what I would like, but with more detail than just Ambient for 6 aisles.
Next time I go, I am going to take a photo of all the aisle banners and hopefully post it on my local Facebook page
