Phil & PotatoWings,
just as an aside to your poinst on free/built in to the price there are some very minor things that should be gratis and no need to build into the price.
Take for example, the issue of WiFi, yes it is very important in this day with communications being conducted electronically.
However, any FBO should have internet access for thier own business purposes. so what does it take to stick a wireless router in a crew room. 50quid ? heck, you can get free wifi with your 2.85 coffee in starbucks! yes an FBO could charge you for use of internet but then that just comes across as petty.
customers will pay a little more for a level of service, however they do get a little cheesed off when the cheap price invoice lists loads of chargable extras.
