Having done Internet shopping for the last few years, I can see I'm missing out on something here!
A few years back in the local Tesco, I watched a couple of lads, maybe 6 or 7 years old, remove all the
12 pack toilet roll packs, climb onto the shelf, then build up the packs in front of them, then wait for
the next unsuspecting shopper!
Wish I'd thought of it when I was 6!
