About a month ago I washed & Waxed a Fordf150 ext cab lariet Big beautiful truck which was well cared for. the gentleman called me yesterday would like to have the truck cleaned up again which is great I charged him 190.00 last time now this time around I know how he keeps the vehicle should I consider charging a bit less? He's the kind of customer that says money is no object but at the same time I'm not trying to take advantage or to be greedy just fair because I would like to keep him as a customer I thinking about charging him 20% less. Please share your views thanks.
