Can't believe someone took a 15-year-old who eats like a 5-year-old to 'Ohana, an AYCTE restaurant, then was upset when the restaurant wanted to charge what it was supposed to. Oh, but they "spent plenty" over the years.
Why do you have a problem with it if the person asked and the restaurant obliged? Maybe you do things that some don't think are appropriate either. I think you should MYOB.
