My Mum and Dad used to go to the Coop too, every Saturday morning, they used to carry all the shopping back home, we did not get a car until I was 14 years old. I used to go with them and the girl would add up all the shopping on a list, with no calculator and put the money and the list into a brass jar that screwed into the pulley on the ceiling, then she sent it to the Cashier. I used to love watching those things scooting across the ceiling.
My Nan also had a gas fridge with a very tiny freezer compartment. She got this late in her life and there was never anything in the freezer bit. He hated frozen food, or as she called it "Ready come at food"
