At lunchtime I cycled about 3km to a chemist in St Pancras to pick up Mrs F's prescription. To my surprise I was given the whole family's prescriptions - one box and three plastic bags.

After leaving my bike at a stand, I couldn't get an answer at Mrs F's doorbell but I phoned the number supplied and got through to Mr F, who told me to put the items through the letter box. Only the box would fit through, but before I'd even got my bike from the stand, Mr F appeared, picked up the plastic bags, and thanked me for my help.
