I don't visit that often however I did spend a day circuit-bashing there during December and the woman in the tower couldn't have been more helpful. She went the extra mile, helping us pick our way around the boggy bits of ground and by generally being approachable and helpful.
Turning up in a car looking for a company once before though and the experience was much the same as Muffins, although throw in a surly unhelpful 'security' guard too in my case.
PS If the airfield is reading this, I would visit ALOT more for fuel & coffee at the bar if you lowered the landing fee's.
