This BMW E39 is owned by a lovely older gentleman, Donald, he is the father of one of my best customers and provider of a lot more referrals, Donald does a bit of cleaning in his sons MOT station 3 days a week, he also makes sure the lads that work there are well watered with cups of tea and always brings me one round at the same time, so when his car had been to the bodyshop next door to have a wheel arch repair, I told them to bring the car to me before he gets it back so I could give the only used seat in the car a good clean for him.
This was not ever going to be charged for its was just a gesture of thanks to the old boy, the smile on his face was the best payment of the year.
