A couple gripes come to mind:
1. An FBO that has no agreements with local car rentals and crew rates at hotels. I've been to a couple like this and am amazed when it happens. I always voice my opinion to the supervisor.
2. Blase' CSRs and rampies. Complacency in these times is unacceptable.
Assume you are going to an airport with mandatory handling and only one FBO. How much would they need to overprice their services
Hmm... Why do they need to overprice their services at all? I'm sooo tired of companies doing this just because they have a monopoly.
