I here what your saying about how long it takes and how much I charge. Been doing paintless dent repair since 1987 and charged people by the size of the dent and most of the time could have a simple door ding out in less than 2 minutes. If they stand and watch it would bother them to pay me my money I would always tell them I could put the dent back and not charge you.
And go ahead and stand on your soap box I agree.
