I needed to visit a post office to get a couple of things sent. I got to the village shopping centre near my work and found a single parking space (which was lucky for once). Then, at the post office I got served almost instantly.
After I'd finished with the forms I had to fill in and paid etc - when I turned to leave a largeish queue had formed.
Talk about good timing - although I think I've now used all my luck up for the year.
