When landing at LFAT or LFAC or... Actually any "Customs / Immigration" airport in France (I've been to quite a few) - you don't even have uniformed men at the airport, let alone coming to greet you! Although some friends have had spot checks, and then they really REALLY do check absolutely everything.
The issue is getting out of the UK, its coming back in! (at least when you land at Biggin Hill as I do) where you definitely have to meet officials in uniform!
