My daughter bought tickets for a concert about 3 months ago. At the time, there was no mention of vaccine or mask requirements.
Now she gets informed she can only attend if she is vaccinated. They have an "All sales are final" statement, but I feel this last minute change could be seen as a breech of contract.
Are we basically screwed and charged by the system now for not complying?
It is breach of contract. If they don't refund the money, take them to small claims court and sue them to recover the money and court costs.
