Hello and thank you for contacting us. This is Dwayne B. and I’m an expert here and looking forward to assisting you today. If at any point any of my answers aren’t clear please don’t hesitate to ask for clarification. Also, I can only answer the questions you specifically ask and based on the facts that you give so please be sure that you ask the questions you want to ask and provide all necessary facts. Please note: This is general information for educational purposes only and is not legal advice. No specific course of action is proposed herein, and no attorney-client relationship or privilege is formed by speaking to an expert on this site. By continuing, you confirm that you understand and agree to these terms.
Anyone can sue anyone for anything, but I assume you are asking if you can sue and win.
Private business owners are allowed to exclude anyone that they want to exclude from their location so long as it isn't for an illegal reason like race, age, gender, disability, etc. They are allowed to exclude you based on not liking members of your family, not liking you in particular, etc. They can also selectively enforce their rules and regulations, again so long as it isn't due to an illegal reason like the ones previously discussed.
If you had ordered food and weren't allowed to finish eating it then you could certainly sue for breach of contract since inherently there is an implied contract that you will be allowed to eat any food that you pay for.
If your question has been answered then I'd offer my best wishes to you and ask that you please not forget to leave a Positive Rating so I receive credit for my work.
Of course, please feel free to ask any follow up questions in this thread. I want to be sure that all of your questions are answered. In addition, once you issue your Positive Rating the question will lock open and no longer time out so you can come back to it anytime in the future if you think of any follow ups.
