Sorry I don,t tip corruption. I have traveled to the Burmese border numerous times always made it in on $10. Hide most of your money offer 300 baht or $10 USD works every time.
Extra $$$ for the military to kill people. Works for me every time they play games. If more foreigners stood up to the B.S more often would be far fewer problems for others. Be polite but firm and most of all learn to say NO!
The long tail boat across is 50 baht for locals. AVOID ! the dodgy characters that approach you at the pier. Try to not go across on a weekend. Take a good USA $10 bill and or 300 baht and hide the rest of your money. Tell them you have a choice $10 or 300 baht NOT 500 baht. The last time I went on a Sunday my $10 bill was in perfect condition but dodgy side kick insisted I give him 500 baht. Since the banks were closed they thought they had me. Basically told them take it or leave it up to you.
