Luckily so far foreigners here have a bit of a special status and no one wants to touch them. Crime against foreigners is incredibly low as well. Most of my friends in Bangkok will not really change their routines as well (but they are not preppers).

Usually what goes with that is envy (more or less) and when the SHTF for real it can turn to the rage and hate toward foreigners, and sometimes (by some logic) they will be accused for all bad that is happening.

So it is good thing to pay extra effort to be very good prepared for SHTF.
