OK, so I went back and looked at the receipts. After some arithmatic, I see that the beverages were included in the food total.
The items ordered & their prices are listed then is a line that says
20% Wonderland Food $12.77
20% Wonderland Beverage$0.00
Then the
Subtotal
18% Gratuity
Tax
Total Due
That's what I get for doing math in my head. I guess the beverage line would have been for alcohol.
