I've noticed at our farmstrip in Hampshire, we get occasional gliders come in, usually from Lasham. When they do, if I'm around I usually stroll over with a greeting of "welcome, kettle's on, anything I can do to help" - the first thing I see on the glider pilot's face is relief. I'll keep doing the same, but for as long as relief is their first response - there's a problem out there.
My experience is probably 60% indifference, 10% grumpiness, 30% a friendly welcome. It could be better.
