Radarcontrol,
The public transport is actually quite good at Humberside..frequent(hourly) stagecoach services to Sheffield, HULL and Grimsby. Also a railway station at Barnetby @1 mile from airport perimeter.
Sandwiches are no more expensive than any other airport. Catering has been improved recently and choice of shops reflects size of airport.
I would actually rate HUY 1st of the airports I've used(others being LGW/LHR/STN/BHX/MAN/LBA/GLA/PIK/EDI/ABZ).
