When I was young supermarkets were tiny places with 4 or 5 aisles - like your city centre Tesco or Sainsburys these days. You were lucky if two trolleys could pass each other. They have got bigger and bigger over the years culminating in the opening of Scotland's largest supermarket last year: Tesco in Silverburn. I knew it was big as I found it harder and harder to walk round last year, the more pregnant I got but today I realized it was definitely too big. While standing between the clothes and the vegetable department, a little old lady came up to me with a trolley full of goods and asked: Excuse me pet, you don't happen to know where the checkouts are or where the exit is in here? - I just can't find them, and I've been all round the shop! Awwwh!
