Kind of depends. One friend of mine will take me out on his boat several times a year. He has never let me pay for gas (and this boat holds alot) and often times if we grab some lunch or dinner he insists on picking up the tab (he does pretty well). If I were to ever detail his truck, without question it would be a freebie.
Same goes for another friend (who also does well). I wouldn't feel right charging him since he always insists on paying whenever we go somewhere.
