One of the many perks of my new flat is having a cinema five minutes’ walk away. Tonight, I strolled down there at five past nine for the nine o’clock showing. Being ten minutes late still gave me plenty of time before the actual picture but enabled me to avoid the adverts for Gillette’s latest 98-blade face-scraper or whatever. Advertising subsidises the cinema’s running costs and I don’t have to watch it. Everyone’s happy!
