My observations are similar to your's Fatman41. Whether the person has a good heart is at the top of the list of their discussion. It also seems to be the thing they quickly tell others such as taxi drivers, service people, etc. This seems logical because it reflects how they are treated by the customer and what others can expect. Whether the Farang drinks or not and how much also seems to be near the top of the list. Again, this can impact how they are treated. I also hear comments about how the Farang dresses especially if it defies the Thai norm of "dressed up"= money and "not dressed up"= no money.
