12. It's not ambiguous. One of the "perks" listed is women. And these women
will be there to serve the men. The obvious conclusion is that the ONLY women who will be there will be the servers. They are clearly advertising only to men, thereby making it an event a woman would not feel welcomed to attend (unless they are part of the wait staff).
This isn't an ad for a bachelor party, but it sounds like one. It's not like playing records backwards looking for messages. It's very obvious sexism. That's why their sponsors are dropping them.
