Why should ramp checkers be offered coffee ?
I have never done that and I never will nor have I had any major problems with any of the inspectors. I'm not impolite or not co-operating but I'm there to do my job and my contract no way in hell include pouring coffee for some wannabe yellow vests asking my license and spare glasses after a 13 hour work day.
Especially not in Nice or Bordeaux, France.
