Um, perhaps I'm wrong, but I'm pretty sure I'm not. There is no place in Mexico which has 95% humidity. And at 100%, you would essentially be swimming in a pool. So if you want to complain about a person or school, okay. But let's not exaggerate topics, like the weather, which are clearly not exaggeratable.

As for what you had to say, if the newbie does their homework and reads the appropriate websites about teaching English in Mexico and what the typical offer is, then being promised the world will easily be transparent. In addition, one can always ask for references. If they are refused, it's a dead giveaway that the school isn't what it's being made to appear as. And in addition to that, visas don't take 4 months. Accepting your boss's excuses for so long was dumb.
