just left with my coffee I was looking forward to. never been so offended in my life. I ordered at the drive thru and when I pulled up to the window the employees had put a sign on their tip basket that blew me and my family away. it had a picture of the titanic and said even the titanic tipped. well it did tip at the cost of 1500 lives. truly tasteless and disrespectful to the loss of lives.
