The discrimination based on accent is obvious to me but the food surprises me.. what kind of food from that region is looked down upon on the coasts?
It isn’t necessarily the food itself, it’s just that the food marks somebody as lower class. For example, not knowing how to order sushi or use chopsticks. Maybe a better example is not knowing anything about wine. People will think you’re stupid or have bad taste. What would you think of a coworker bringing bologna and ketchup sandwiches to the office?
But I’m also from the Midwest and don’t know how to order sushi.
