Shop flags

I have been walking around downtown for about two hours, from Dupont to the Mall to Georgetown, stopping once in a while to browse shops or sit for a bit. I have not been counting exactly, but noticed early on that restaurants and grocery stores specializing in foreign foods or merchandise very often have American flag stickers in the window, or if they have the flag of another country flying in advertisement, an American flag is usually flying beside it. Stores or restaurants whose nationality is not specified, which are assumed to be “American”, do not nearly as often display any flag.
