They tell me it's the credit card fraud capital of the country.

Happened to me at Rusty Pelican at Key Biscayne. Someone there changed my tip amount. The only way I caught it was because the CC I used was actually a debit card and I review my bank account regularly.

Had it been a credit card I would have long forgotten what tip amount I left.

When I called the manager changed it back without question. I guess he is used to this happening.
