So where do we farangs stand on the food chain here..
That's actually an excellent question, to which even some of the longest inhabitants here may not say they know the answer to 100%.
There are probably many differing opinions on it and some probably more complimentary than others. We certainly do fit in somewhere, and on average it's probably generally in the middle somewhere. However, imo, it is still dependent on the same superficial things they quantify/judge themselves on, ie appearance/politeness/disposable income/job/Modus Operandi/possessions that you have been approved for having on credit and so on.
We are certainly tolerated and afforded a certain standing or status if the jigsaw fits, but there are plenty of foreigners that fall into the garbage section, of which we all know of too well, and are treated as such by the locals.
