Side Note:
It's easy to say "I charge this" or "I wouldn't work for that amount" but different areas of the country dictate different fees. In Austin I based all work on $40 per hour and turned down those that wanted to haggle. Where I live now that dog don't hunt.....$25 per hour is it with a few exceptions. There's just too much cheap labor here. Do they do a professional job? No, of course not but understand that here a wash & wax IS considered a detail and it's about $45 FOR A SUBURBAN!!!!!!
In short I think they are getting to you but not knowing your situation makes suggestions difficult at best.
