I had reservations for 3 via Eventbrite for the Story Telling with Drag Queens. We were turned away at the door due to over capacity. The person at the door claimed he didn't know anything about such reservations but did mention one other person had a similar reservation. Even though I had a confirmation email to prove my reservation we were not allowed in the venue. Very disappointed and confused.
