Flew a rescue to Des Moines recently. No discounts for Pilots N Paws and was charged a ramp fee to boot. I asked if it could be waived since I was doing a transport. The response was "no way". Although I was the only airplane on the ramp, I was parked a long way from the entrance. I will exercise my right to go elsewhere in the future and will take my wallet with me. Hope others do the same.
