and thankfully there is always one that wants to do the right thing for other humans less well off than them. Try it one day whilst counting your baht, it's liberating.
You hear about this 'norm' and 'going rate' but I don't know a single person who would get away with it. In the arse end of nowhere possibly, but if I or any of my friends expected someone to work all day in a garden, or carry our repairs all day, or clean the house for a full day (spring clean etc) and pay them 500 baht, let alone the ludicrous minimum, we would get laughed at and spend all day looking for that elusive person and end up doing it ourselves! The days of the Raj are long gone!
He understands it perfectly and you've never run a thai business. I've employed many staff in the home and business here and loyalty is the toughest thing to buy. Treat them well they'll stay, give them the bare minimum and you will forever be looking for staff and the ones you get will do a crap job until they find a nicer person.
Have absolutely no idea why you think the pound is pegged to the dollar, care to explain? It's scary how many people are convinced they know it all but are clueless. A currency is largely, but not exclusively, dependant on how much cash you have in reserve, ie if the shit hits the fan economy wise, your capability of buying your way out of it - now go and google it! Thailand has more than the UK or Germany. The baht isn't going anywhere and is only a fag paper behind the Yen as being seen as a safe haven.
I don't blame you, but its mainstream now and whilst the whole thing is nuts the fallout of any collapse would be too much for major economies who are regulating it more and more. My opinion it's safe to jump on now, the predictions over the next couple of years by respected analysts are nuts!
