Yeah, folks who don't grow up in rural towns or grow up lower-class REALLY don't get this.
They get the exact same treatment that you'd get if you were the 14-year-old kid working in the shop with his uncle. You get called names, teased, and tested—it's part of the culture.
But instead of recognizing it for what it is, they try to apply labels like "sexism" to it. Or they're "resentful for being tested" as if any shop jockey feels _confident_ the first time they fix an item for a customer.
If you don't like the culture, leave it. Stop applying your labels when you don't even understand the world you stepped into. It's like labeling the Native Americans as "savages" just because they don't fit your sensibilities of how the world "ought" to work.
