An unexpected job

Funny how things work out.
I was supposed to take Karen to the doctors this morning however events changed and my morning freed up, what to do instead?
The phone rings and this company asks me to photograph them as the photographer who was supposed to do it failed to turn up. Can I be there in 1/2 an hour, can do.
Got the job, done and dusted, results back to them by mid afternoon.

Well that was a surprise and yes I put in a invoice for work done
