I totally disagree with this comment!!!
My friends and I are regular customers for Thai tanic.. The food are great beyond the decorative food, also the taste are unique and authentic.
The problem with your credit card might happen when you calculate wrongly like....
total before tax will be $15.50 you put 2.32 but you write down the total like $18.82. If you waiter what you gonna do when this situation happen.
For myself, I believe that $1 or 60 cents means nothing when you compare to the reputation. Then, before you blame someone make sure that you do or write everything correctly
Most of the time whe you pleased with services and food, it's MANNER to pay at least 18-20%(in case that you are american).
