Well If They Don’t Mind…
I used to work for a PR agency. Every month one of our clients wanted a handful of photos re-sized for their website; nothing fancy, just setting the width to 500px in Windows Photo Manager.
It was maybe ten minutes of work every month, but the contract said the minimum amount of time we would charge them for was one day – and this was for the full team too, not just me. It must have cost them several hundred pounds every month. I showed the client how to do it several times and explained that they could save a lot of money doing it themselves.
They didn’t seem to mind. In the end I made sure I got it in writing that I’d informed them of their options and let them get on with it.
