Assaulted and disrespected by speakeasy employee

Tonight I celebrated my birthday with my closest friends. I turn 27 on Tuesday, 15 May 2018. We went to Speakeasy just before 17h00 to watch the rugby. About 20 minutes ago I went out to the parking lot to put my sunglasses in the car. I went back inside to Speakeasy to the table where me and my friends sat for the last almost 2 hours. One of the bouncers came and grabbed me by the arm and physically assaulted me. He asked me to step outside and to show him my ID which I then did. He told me that I am not allowed inside and I asked for the manager. He told the manager I was rude. I confirm that I did not even speak to the bouncer before this encounter. He then told the manager I refused to show my ID when I entered. I confirm that he never asked for my ID and I am 26 years of age. I confirm I did not have one alcoholic drink at speakeady tonight. This is ridiculous. I go to speakeasy regularly. Not only was I physically attacked but also embarrassed in front of my friends and other people and treated with disrespect. I expect a formal apology and compensation or this will be taken further.
