Different attitude towards things for sure... they Americans are always in too much of a hurry... it's the journey more than the destination.
Still remember hearing a American group complain about service and the waitress collected the menus saying McDonalds is down the street.
The locals showed me how it's down... relationships and drink money... that is what they do for just about any services... always a small tip or food item...
Feeding workers coming to your home is almost expected.
When I called for my final in Austria the head of the building department with chief inspectors show up... I was told I needed to have Bier, Bread and an assortment of coldcuts and some pastries for the road on hand..
I thought it was a joke but was informed otherwise...
Put out a nice spread with table cloth... had plans and permits laid out and process lasted about 3 hours... 45 minute tour/inspection and the rest really standing around chewing the fat.
The approve set of plans and all docs were designed and drawn by me... plus I did interior electric, etc...
It pays to get trusted local advice as to how business is conducted locally
