I have had this one customer who has been with me since i started my own business for the past 4 years now. Most of you know i attend college and im graduatiing this year, so i love the money detailing makes me while going through school. The customer Im dealiing with has 3 black cars that i do weekly washes on/wiping down the inside. He recently started giving me 250-300 per week which i think is a little to much money. I left money behind one day, and he called very angry and upset and said never do that again. I always make sure his cars look their best, but i still feel he is spending to much money on me washing these cars. What should i do, because i feel like im taking advantage of him? I told him it would normally be like 45 a car, but he says that is to cheap. most of the time to, im only doing 2 of the cars, cause one car is kept in the garage which he really never drives. Somtimes i will wash one car and he will give me 600 dollars on numerous occassions, and i feel awkward taking this amount of money. I belive the guy has a pretty good cash flow, but his cars are actually quite common. 2 avalanches (one he gave to his unce so now he has 1), a small mercedes benz and a corvertte.
