No, I don't.
And yes - call them. But as I asked earlier, please explain how if a CC report, with your ID, shows total sales - such and such and total tips - such and such, how on earth you could claim less???
I've been messing around online trying to find out the procedure at Outback, but I'm just sick and tired of looking. When I called, they assured me that they follow the law and that servers are required to declare all the tips they make. It was a standard, it's none of your business (LOL) type response.
I had talked to one of my friend's nieces who works at Olive Garden though. She backed up what you said about credit card tips, so I am officially conceding that point. She said that when she cashes out each night, the register makes them report their tips. Credit card ones are automatic, but she said everyone she knows claims such a small percent for their cash tips that they really don't turn in much over 10-12% of total sales per day (and she added that some probably don't turn in that much even). Oh and she said it's customary to tip out X % of gross sales to busser, bartender, etc. She said that's not based on tips at all.
So here is my official apology on that point. I am sorry and am eating crow.
I do want to say however that not every restaurant turns in credit card tips even though they are chain restaurants.
