In Bahmian Creole there's usually not a formal way of saying things, as it's a dialect of English, and so finds common informal usage. If you wanted to greet someone informally you could say, "Wha-choo sayin' bey," or "Eh-ree-tin' cool?" It's typical slang with a Bahamian twist. Usually Bahamian Creole is standard English with a thick Bahamian dialect, and the occasional Bahamian-ism thrown in, such as, "Bey," (man/dude/bro)
"Man-ay!" or "Muddoes" or "Muddo-sick!" (Good god!/ No way!)
and many others, theres a long list of such terms, but to really appreciate them, you have to hear them in context.
You can say "Good day, sir" in Bahamian Creole as a polite greeting.
