But we aren’t talking about just telling your manager. There are so many layers of management and bureaucracy with larger corporations, especially ones with a structure like McDonalds’ franchise model, that these complaints will not make it to the decision makers.
They will eventually. Years ago Starbucks used to insist that customers specify 'tall, grande, or venti' for their medium, large, and x-large cups, to the point of arguing with the customer if they just asked for the large. They abandoned the practice some years ago, presumably due to feedback from their counter staff.
This is also incredibly weird to me. There is nothing in that post that shows any indication of them not being a native speaker. You just agree with their underlying point so you're giving yourself leeway to ignore the parts of what they said with which you disagree. However, you can't actually admit that bias to yourself or to me, so now you're completely fabricating stories about them being a non-native speaker. It doesn't matter to you that this justification is entirely circular, they didn't mean "hostile" because they're a non-native speaker and they're a non-native speaker because they said "hostile" when they didn't mean it.
Same here.

A lot of people are seemingly skipping over OP describing their behavior as creating a “hostile atmosphere”. That is inherently rude.
