About over paying and over tipping.
I already explained the following in (much) earlier posts, but it seems that a reminder is necessary. In Thailand, you don't get respect from locals if you over pay (or over tip).
When you pay the right price (that's about the same price than a local or maybe a little bit more in some occurrences because, as a foreigner, you are, on average, much trouble to deal with), local people will think that you are 'chalat' (ฉลาด), which means 'clever'.
If you over pay (or over tip), then, Thai people think that you are 'ngo' (โง่), which means 'stupid'.
If you are too stingy (for instance, when you haven't taken into account that you got more than a local for a certain service and still you insist to pay the same price or lower than what a Thai would pay), you are considered as khi-niaw (ขี้เหนียว) or 'cheap Charlie'.
Sometimes, you may also be called a 'cheap Charlie', even if you pay the right price, by certain greedy locals who were expecting to make a better benefit in a transaction with the supposedly stupid foreigner, but it's usually easy to understand that it's not really the case in this kind of situation as it's mostly said jokingly.
On the contrary, when you are called "jai dee" '(ใจดี), which means 'good heart' or 'generous', it's often because you over payed for a service or goods, and more often than not, you are actually considered as 'ngo' by most locals.
And remember that the monthly average income per person in Thailand amounts just a little bit over 13500 bahts (13,581.1 THB for the last quarter of 2014 - source: National Statistical Office of Thailand: [url=https://www.bot.or.th/English/Statistics/Standard/SDDS/Pages/sdds.aspx]https://www.bot.or.th/English/Statistics/Standard/SDDS/Pages/sdds.aspx[/url]).
Then it Depends on the Industry
[QUOTE=LAGuy5;1692270]Based on your response, it appears the answer to my question--"Do you have specific evidence that a high tip in a mom-and-pop restaurant is often seen as an insult in Thailand? Or is this just your speculation?"--is it is just your speculation without any specific evidence. Of course, any of us with extensive experience in Thailand knows that tipping practices are different there than in the United States and that Thai tipping is as a rule less generous, but that is a different issue from whether over tipping can be seen as an insult in certain Thai locales.[/QUOTE]This is great information overall, but if we center on the P4 P industry then a different set of rules apply. I had a lady stop In the middle of the soapy and tell me that she expects a tip and that is all the money she makes as her share of the soapy was very small.
