Sweets – guess what most of them come wrapped in plastic or worse. TIC TACS IN A LITTLE PLASTIC BOX WHAT ARE YOU DOING YOU FOOLS>>> So I have stopped buying themI know – it sounds truly noble but its really not that bad.

I can still buy chocolate which is foil and paper wrapped – and there are sweet shops in Queensgate market that selll unwrapped sweets by weight in paper bags.
I can buy cakes from the bakers with no wrapping at all and they are practically the same as chocolate bars.
