snuck a $3.50 credit card usage fee. Fortunately, we had cash so they had to take it off. When asked, they said it was some type of new local tax the credit card company was charging. After, we asked if they had posted a notice in the waiting area or on the menu that they were adding this fee due to regulations. She said fine and huffed her way to get our change. I was suspicious cause just a few hours before we had stopped at Sam's Club cafeteria and ordered a pizza and drink and they did not have to add $3.50 for the credit charge.
