I've seen grown men take a dump on the side of the street in Saudi..
Busy streets and they act like it's normal.

I think the peeing in the street thing has been covered (I've spent enough time on Market St in San Fran).

As far as these guy's being able to drop you at any time as you are just a contract pilot, well, compare it to what the US airlines did to their employees; jobs, pay, pensions. . . all gone. It's not an argument, it's an excuse.

Again, ex-pat flying, anywhere, is not for everyone. If you think it'd be worth a go, a bit of adventure and a good pay check, then go for it. If you like the comforts of home then that's great too. Different strokes, as it were.
