I had one that I do inside and out, and went by in light rain one day and the guy said,
"Just do the outsides today, with the rain on"
I tought he ment just do the insides, and went to correct him...
"No just the outsides"
I tend think people make up excuses like that when they are short off cash and are alittle embarased by it. So let it go, but if they persist to waste my time they get dropped.
