Ah yes, what an adorable Facebook group.
I’ve almost no sympathy for this one. We often get all high and mighty about people learning another language for our convenience. Coming out of an American’s mouth, it’s appalling. Chances are good anyone joining the aforesaid group is fluent in exactly one language –English. Chances are equally as good that they’ve not traveled enough to know what it’s like to try to get by in a day to day situation in one’s non-native language.
Unless and until you’ve followed complex instructions in a language that is not your native language, you don’t get to have an opinion on this.
I’m saying this as someone who does speak more than one language by the way. My French is good enough to do minor tech support, I can follow a Karate class taught in an Okinawan dialect and can understand Spanish well enough to follow a movie without reading subtitles.
Those are easy languages/situations, I have a talent for languages and it’s still rough. My bank account, credit rating or legal future are not involved in a fine understanding of any of those languages. To expect someone to “just pick up” English well enough to handle this is absurd and self-righteous. Especially out of people I expect don’t have any talent for languages themselves.
Show a little imagination and empathy people!
 try it sometime on four years of high school French learned at a time before most computer terminology was even invented
 Ya, body language and visual cues to help!
