as i have been recently living in bangkok i thought id pass on a few tips,or things not to do,number 1 if you drop a coin and it rolls away don't put your foot on it ,why you risk being arrested as the coin has the kings head on it and by putting your foot on the coin it is considered disrespectful to the king.2 smokers,the thais are aware of the dangers of smoking even though the price of cigarettes is about 1.5 dollars for 20 ,but they have no smoking zones which are signed ,the signs are that small that you cant see them and you risk a hefty fine if caught,most of the thais are in debt and have no qualms about asking for money there debt is mostly to loan sharks who charge 20 percent interest per day and is collected every day by stand over men,who are sub contract collectors and if they dont get there quota have to put the money in from there own pocket ,so some bashing is done, .why you may ask dont they go to the bank for a loan,well if you have never had money to put in the bank the bank wont give you a loan thus loansharking is a thriving business,id say 2 out of three tais are tied to a loan shark,so asking for money is a way of life.teeth a screw in tooth will cost 1000 aud a filling about 2dollars aud.there are other things i have found out by living with the people but they should not affect you as a tourist.the people are affable,and living in a not to good part of bangkok i have not had any trouble yet. hope this will help somebody contemplating a holiday. i forgot water the thais don.t drink the water from the tap there are reverse osmosis machines dotted around the place where you can fill up cheaply.
