Parking Receipts

Much mention has been made in several posts over the past few weeks about the fact that Mike Castro does not give a receipt for parking at the ranch. I'm curious, has anybody ever asked for one? (I do not use the ranch for access to the springs, so I've never tried). What if everyone on the board here were to simply say in a very nice manner "May I have a receipt, please?" If he refuses, then turn around and don't park at the ranch - even if that means not going to the springs that day. I realize the the people reading this may be so small compared to the total number using the ranch so as to not make an impact, but it seems to me it would be an interesting experiment to try out for a while.
