That always feels incredibly forced, and very very fake.
But what do I know, I'm British ..!
The OP was making a general observation about the United States as a whole. Picking an extreme example like Disney is a Hasty Generalization fallacy.

I suspect the confusion comes because people assumed I meant Disney stores in the states.
The fact that workers are trained in cheerfulness, and are given a set of phrases they must say, and that they say these phrases all day everyday to every single person they meet makes me think the cheerfulness is inauthentic.
Good grief.
As would one's inability to understand eye contact and body language.
Have you considered the possibility that you are presenting yourself as what they see as rude and unfriendly, thus leading them to be uncomfortable while serving you?
Well, we have two alternatives here:
1) A person who grew up in a culture has a gross misunderstanding of the norms of that culture.
2) Someone who grew up in a totally different culture has a gross misunderstanding of the norms of that culture.
Now, which of those two seems more likely to you?
"For example, my comment about eye contact and body language was actually an insult meant to imply that you lacked the ability to read either."
Oh, I got that. I was just attempting to be polite by ignoring you being a jerk. Maybe someone is forcing me to do "unpaid emotional labor" or something.
Once again: it's not them. It's you.
Your response was to suggest that it is actually my fault and that I am behaving inappropriately.
You see nothing insulting about that? You are the jerk here.
Some people actually do genuinely like other people and enjoy helping them.
That you find it "inauthentic" may say more about you than it does about the service workers you're encountering.
