After drugging them they stole belongings. Sounds like the man in the bus was put to sleep using same stuff. So it is the water and not a gas.

I can see the Pattaya beach lady drugging his client but to do it in a hospital! Where can I hide? I will now want to open my own beer etc.

I used to carry lots of money. For the last year I now carry no more than 4,000 baht. Good thing since all these happenings are worrisome to say the least.
