No. Here’s the issue with 1099-K for a restaurant. 
it’s a Gross number. Meaning the 1.45m 1099 I just got has 78K in sales taxes in that number. Has over 200K in server tips in that number. 
has 15K in gift cards in that number. 
Anything rang on a customer card is in the number. Tips and taxes. Now before you tell me that gift cards are liability on the balance sheet, not counted until redeemed yes I know, and we pay our tips out daily anyways….relax. 
the original question was what if I report less that the 1099K and you said don’t you have any cash sales. Yes. I do. But this why in restaurants ask this question. My number is 300K less then the 1099.
