I noticed that most Americans on Reddit nonchalantly mention the same IRL businesses (restaurants, stores, etc.). It's like if everybody lived in the same village. People say the name of the business and most of the time they don't even need to say that it is a restaurant/hardware store/whatever. Sometimes they'll just say "the place whose workers wear shirts this color" and it seems to be enough information for all American readers to know exactly what they are talking about. It's as if every village had the exact same businesses, and local businesses with local owners were the exception, not the rule.
Is it really like that in the US, or is it an artifact of Reddit subculture?
