I tell them I'm an American when asked.
People are fundamentally the same regardless of where they live, and anyone that judges anyone else based on their nationality is being an ignorant jackass. I handle it as such with the appropriate tact for the situation -- most people are cool.
The ones that aren't are morons and not worth wasting time on.
The US only occupies countries hostile to the US. Guyana is already allowing US companies to extract their oil under license: they're going to get the Kuwait deal.
-- and "stabilizing element" in the middle east. Israel gets a lot of leeway because they've proven they have a capable military, intelligence agency, etc. And they're not at all squeamish about using them.
-- to make it less offensive to the Republicans and a handful of "moderate" Democrats so it stood a chance of actually becoming law. It didn't even pass in its original form due to a Republican led filibuster: the Bill's backers didn't have the votes to overcome it, so they had to make concessions. Unfortunately that's how Congress works.
The idea Democrats could have passed a bill for universal healthcare is absurd. Any serious attempt to pass it would have been shut down. The parties aren't homogeneous entities: they're made up of individuals with their own agendas.
Your example is from one of this industries notorious for being toxic -- that doesn't make it right.
"Why would you think that's even remotely acceptable? Now I have to go apologize and possible comp a meal." Depending on the circumstance: take them off that table, send them home, or fire them. Being in control of themselves is one of the defining aspects of leadership, and being abusive is the sign a "leader" that isn't.
If they start being a dick: sure, game on -- so long as you're not demeaning yourself doing it. But most people are capable of a degree of self reflection and accountability once you make the situation clear to them, and they deserve that chance. Sometimes people don't even realize they're the ones that screwed up, even when it's obvious to everyone else.
It's possible to be assertive and assign responsibility for a screwup without being a dick. "Being a dick" is the nothing else has worked option, not step one.
Some instances run profanity filters.
If there's water available you don't have to carry it in. Treatment tablets and filters are lighter than water, and let you make potable water as you need it.
It's great Citroën is making a small, cheap EV ... but why did they make it look like a cross between a Fiat Multipla and a pug?
That thing is ugly.
