Does everyone else get ripped off paying 18% gratuity and convenience fee when you have 2 people and pay cash? Or is this something they do to just tourists?

Never noticed this, but never paid much attention 🤷

The convenience fee comes off once the server enters that the payment was in cash. When you first receive your check, the fee will be shown, but your final receipt, if you paid in cash, will not have that fee listed. Also, if you were dining in or carrying out, there should not be an automatic gratuity, especially for a party of 2. If you are being served on the beach, there is a 20% automatic gratuity.

I didn't experience that there.
