There's plenty of people and businesses in PA who don't speak English. I've met people's grandparents who only speak eastern European languages like Czech and polish, third and fourth generation Mexican families who always speak Spanish to each other, Puerto Rican restaurants who only have menus in Spanish, Italian neighborhoods with a ton of Italian speakers, and so on.

Bonus points: I've never lived in Philadelphia or Pittsburgh with huge immigrant communities, all the examples I cited are in cities under 75k in PA
