I went to dinner with a friend had one glass of wine and we each had an entree. The bill came to 48.69. I added a 8.00 tip or around 20%. When I checked my credit card 2 days later it said our bill was 123.69..I almost had a heart attack. Apparently 80.00 was added for the tip. I called the manager disputing this amount and thankfully had the receipt but not the tip portion for my receipt. The manager sounded surprised that I didn't want to leave 80.00 for a tip or 200%. He actually argued with me about it. I think that is such bad customer service and so completely ridiculous. I told him to clear it up or I was going to dispute it with American Express. I really think that these people need to use some common sense.
Just my two cents.
