Pilot activated (controlled, if that's your terminology) lighting.
Some form of UNLOCKED building to meet passengers/taxis/friends that has clean toilets & at least a water fountain. Some comfortable seats & a table that can be used for (re)flight planning/eating one's lunch.
No locked gates/fences/security that uselessly prevent me from accessing MY aeroplane!
Tie down points. Not necessarily supplying chains/ropes, just somewhere to attach them to.
24hr fuel. Not a bowser & refuelling bloke. A fixed pump & self access fuel card/credit card facility is MUCH preferred.
Public phone that takes money not just those bloody phone cards. Local taxi numbers AND the region's briefing office/ATC contact on prominent display.
Prominent local information point: Accommodation, transport, places to eat (for all budgets), places of interest.
Very, very PROMINENT signage about where all the above is located.
If aerodrome fees are necessary then reasonable, no excess 'services' supplied that we don't want or need. Various ways to pay. With receipt.
As for a 'hangout': A cafe that's cheap, a watering hole, a flying school/aero club that has a broad range of things to do (competitions, fly-aways, trainging for 'fun' things eg aerobatics, formation etc etc), a maintenance facility, hopefully the drinking spot has an observation area (indoor & outdoor) that lets people watch the traffic while they merrily drink. Maybe even a BBQ that people or the club can use.
Things not desired/necessary (some silly CAA rule might require it, but not me...)
Don't care what the runway surface is. It can be tar, concrete, dirt, grass, gravel, ice or whatever. As long as the condition is adequate then whatever is cheapest for you to maintain.
Security bullsh...
None of this FISO or A/G carry-on. What an irrelevancy to most operations - apart from the UK's bloody bureaucratic rules.
Idiotic local rules eg hi-vis vests. There is NO evidence that these reduce accidents on small airfields.
Fire services. The number of times that an on-airfield service has altered an outcome for GA ops is miniscule. The bulk of the western world operates private & commercial ops into no-services airfields with at least equivalent safety.
