'Murican here. We're home to every personality under the sun - if you feel like the person you're dealing with is an asshole, they probably are. Disengage and move on - you'll find pleasant people.
Given the political disaster we're about to dive into, you might want to wait a bit to gauge how we treat our guests over the next few months - we've definitely set the stage to go full Nazi, whether or not we actually do remains to be seen.
Fucked up politics aside, welcome aboard if you ever decide to visit!
