Was harassed a few days ago on my birthday

Justin and I were at our favorite sushi restaurant, hugging and kissing and doing what we do ( but not over the top). These people came to sit next in the next booth, and proceeded to argue about who wold sit facing us and have to "look at that". Then, the poor unfortunate bitch who had to (poor thing), gave me disgusting looks the whole time. When we were done, I stood up and walked to their table and said " I hope someday you will open your minds and have a little bit of fucking class". They looked at me like " omg how dare you what are you talking about!?". I really wish I did not use foul language in my confrontation, but I was so heated up. But, at the same time, I wish I said more and really lashed out.. Lol. Ugh. Stupid ignorant people.
