Had dinner last night.  I ordered calamari from our waiter who called himself \"meatball,\" and I  asked if he had tarter sauce.  He said they did not have tarter sauce. I asked if he had any mayo (I could make my own).  He said to me \"I'm not making you tarter sauce,\" then turned his head and mouthed some obscene remark.  I was very insulted.    After dinner I paid the bill and gave him a 10% tip instead of my standard 20% and on the check I added a message that he insulted me and I'd see him on Yelp.  He ran after me where I was standing at the curb, irrationally and aggressively talking about the tarter sauce.  I tried to explain that he totally missed the point, and that it was how he handled my request, but he wouldn't listen.  He told me to get off the  (public) property or he would call the police.  My husband thought \"meatball,\" a 350 pound guy, was going to hit me.  The whole scene was a nightmare.  This is the first time I have critiqued a restaurant on Yelp and I was astounded at the depth of the negative reviews.
