I ran across the road, narrowly avoiding oncoming traffic from the right, to reach the bus stop before the arrival of the number 11. Although it was a Sunday, the bus was packed. Most of the passengers were on the bus for the same reason, and it was nothing to do with travel: they needed to use the on-board photocopiers.

I later mentioned to my sister and brother-in-law that there would be great commercial opportunity in establishing a chain of Sunday opening only copy shops in university towns across the UK. They both agreed.
