As I said, your fees are higher. I understand your position. We have patients that pull those same antics with much smaller amounts involved, so I have no doubt you have to fight that battle and they are much quicker to try and "stiff" you. They figure they can avoid ever seeing you again in their lives, so they decide they should get out of paying you since they are ok now. I know the mindset.
Nice extra idea about the lawyer fees and collection fees.
