Good treatment comes from good interest by the visitor.
I have seen this time and again. I have found that using what French I have helps locals see my interest.
& doing things like trying to track down a place where I might hose down my camper or have someone in a vehicle service business wash my camper after I had done a gravel/clay road in rainy weather. Believe it or not it seems that folks will put that effort off. So, my request was asking for help the same as I would want at home. The gal who did the work wanted to make my camper so shining clean that I could take into a competition.
Again taking an interest in where I was at the time. For comparison, Baie Comeau, QC or Skagway, AK.
