I'm on a tropical island in the Caribbean...and the staff here all talk in "island speak".
Surely it's expected occasionally I'd miss a thing or two--like when our server asked "Would you like sparkling water or stale water?"
Because I'm not ashamed to ask when I don't understand a question, I replied, "What's 'stale' water???"
Ummmm....that would be STILL water :/.
I never knew it had a name.
