Here's some tips about formal language:
1. Usually, it's best to replace abbreviations with their original word. For example, if you wanted to say "it's", you'd say "it is".
2. Use vocabulary words that are more descriptive. This doesn't nessesarily mean more complicated words. For example, if you were to say "Jellyfish can live without causing harm to people", instead of "live", you could say "thrive".
3. This is just a Grammar mistake - "jellyfishes" isn't a word, but "jellyfish" is (just like "fishes" isn't a word).
Hope this helps!
I would most likely calmly tell them that I am a citizen of the United States too, and I demand a table. If they still will not seat me, I would probably calmly exit the restaurant and find somewhere that will. That's on them for not seating someone because of their race or culture.
Hope this helps~!
