Pier A made an unauthorized charge into my credit ...

Pier A made an unauthorized charge into my credit card. I went to celebrate my birthday with friends this past June 20. We were trying to get waiter/waitress service into the outdoor seating area, but it was impossible. After a long wait, we finally sat outside but the outdoor bar serves only beers, so we have to go back and forth several times to the indoor bar for drinks. By the time of the charge at the bar, we added only $1 in tips due to the bad service. As a surprise, Pier A charged me 30% extra in tips even though I did not authorize it. Several days after, I went back to Pier A to understand if it was a mistake, but they did not even apologize! It is a shame that a nice location is not enough to compensate such a bad service, treatment, and unethical behavior.
