Of course as people pointed out, this is far from a uniquely American thing. Also, I’m sure by American they mean the USA, but “Americans” are inclusive of north, central and south America. Here in Europe, we also expect people to speak English as it is the universal language.

As a side note, it is also often commented that Americans (USA Americans) can only speak English. This is a narrow view that primarily broadly looks at white Americans and ignores the fact that the US is a huge melting pot of cultures and for many US citizens English is their second or third language.

It goes without being said, the contents of the picture should never have a reason to be written. Don’t be a dick to people trying to help you.
