Conversation with the box office of Ulster Performing Arts Center about mandatory vaccination to attend a show

. I received a phone message last night saying that a show I bought tickets for early last year was rescheduled but would not allow me in without a vaccine card for “Covid 19.” The conversation went on 15 minutes, half with a regular CS rep and then with the box office manager. The call cuts off, and when I called back, they would not answer. Please feel free to share.
