I spent the morning working behind the till in the RA Shop. It was slightly scary learning the mysteries of the till system, remembering to ask if customers are Friends (they get a 10% discount), putting in my pass number, watching the amount of time people spend browsing, seeing the huge pile of catalogues gradually go down, cack-handedly trying to put postcards into a paperbag, and enjoying the camaraderie of the other shop staff under the eagle eye of Ramon. Someone asked me if I was a regular. They could probably spot that I wasn’t. In fact, the last time I served behind a till was driving an ice cream van across the South Downs.
