I could fill a book with my "adventurous journeys" in LOS. Sometimes one just had to laugh or cry. Probably the most annoying was turning up with a prebooked and paid for bus to Surat Thani only to find that they gave it to someone else!. My GF got us on the next bus, or I'd have had a melt down, which is never a good idea in LOS.
The most mind boggling was finding that my GF couldn't go on a bus because she was Thai.
The absolute worst was being scammed onto the wrong bus to Pattaya which stopped every 5 minutes to pick up passengers and broke down less than half way to Pattaya. Had to wait ages for the next bus and stand all the way to Pattaya. Of course we didn't get a refund or an apology.
Trains were even more adventurous, but too many stories to tell on here.
That's why I loved Thailand so much- everything was an adventure into the unknown.
