My mum used to take us to the local florist. It was more than a florist though; it sold things like bird seed in little plastic tubs (which I used to stand and push my hands through - I still love that feeling to this day). They sold dog leads and I used to save my pocket money so I could buy a new one every now and again for my little toy dog that I carried around. I still remember the smell of the green oasis stuff that the flowers were stuck into, and the smell of the bird peanuts. They had a lovely, elderly black and white cat called Crackers who just LOVED the strokes. We called it 'Cracker's Shop'.
I also have fond memories of our local Safeway as it was the first time I was allowed out unsupervised. It was only to buy a pint of milk, but MY GOD I still remember the fear that I'd get to the till and not have enough money.
I'd love to hear about other's favourite / most memorable childhood shops.
