Sounds like a right a***hole. The guy who did similar in Japan got a visit from what I remember from the Yakuza. He left the country not long after that.
Two things. First why are you saying 1 million baht? No one cares and it doesnt make you look good. Secondly if you take that amount they will want to know where you got it so I assume you have an answer to that question and if that exceeds what you are legally eligible to bring into the country you better have a real good verifiable answer. If not they are more likely to report you to the police.
Reading the comments I can only assume Americans are happy with sleepy Joe. Maybe they need to stop taking so many tablets and vitamins, it is affecting them.
Maybe the gym you used was badly organised but the one I go to is very well organised. On the other hand it could just be your expectations were not met.
Any sort of physical retribution as you suggest is unlikely. It is now in the open. Had it not been disclosed then there may be a possibility of what you suggest.
I know it is annoying, I get them as well. I just put the phone down and let them talk away while I go and have a coffee. They soon give up and go away. Additionally you are stopping them from scamming someone else.
No never. Even went to work when I was diagnosed with Malaria. Most of the ones claiming mental issues probably have got them but only because they are lazy.
