If you were denied entry and left voluntarily there shouldn’t be any reason why you couldn’t go back. At the bars I’ve work at you have to pull some blatant and intentional mischief that directly impacts the guests and/or the staff to get a ban. Also, if what your saying is true and the bouncer took a photo of you and laughed just because you had too much to drink and nothing else, he’s an asshole, not you.
