Thank you, I will be super careful from now on. It was a proper large restaurant and the kids very friendly so I never imagined I should be careful. But I totally agree with being cautious.
Yes, Pattaya is a very funny place. I personally hate it, but it is one area of Thailand (which on the whole is normally fine) that you do need to be extremely careful. When you said they were googling the camera, I could imagine dollar signs in their eyes. When you consider that a waiter will probably be paid 6-15,000 Baht per month, combine that with heavy drug and alcohol abuse in some areas, then it is easy to understand why a 350,000 Baht camera could be very attractive.
It is not just the locals, but there are some completely insane foreigners in Pattaya too.
I love Thailand, and do not want to paint the wrong picture, but in some places it does pay to be careful with expensive items such as jewellery, cameras etc.
If you are still in Thailand, you will get to experience the Loy Krathong Festival which is mainly tomorrow night. Enjoy!
