Dreadful, your instincts were correct. We have to have a way to alert other ladies that predators are present on the premises, with alcohol served it will be a matter of time someone will be assaulted. Never be alone or all the ladies leave the premises together citing personal safety!
It is a good idea all ladies leave together, specially in events like that one
Such an incident should not go unnoticed and be taken up with the company to ensure safety of the patrons and staff. IF the company won't deal with it then you and all the ladies concern can take it up with the Press and on social media websites. Nothing like the threat of bad publicity to persuade the company to act or watch their reputation take a big public hit.
Follow up.
I made a big scandal and made it public knowledge with all the employees, the man was fired from the company and another man also said that he wanted to apologize but I said that it was better that we not see his face here again
Awesome! You got some results. I would be tempted to see that these men arrested and at least accused for assault on their records. Unless your experience was but last in a career of assaults, you'd know what to do from here and prevent another woman from being assaulted.
