Flushing Oral And Maxillofacial Surgery

I came to these dentists because I needed an extraction which would have required sedation. I had prior recent xrays which they refused to accept. After taking my money for their mandatory panoramic xrays and an exam ,they refused to do the surgery because ,although I had transportation home , I had no one to accompany me. At no time was I even offered the opportunity to sign a waiver saying I would not hold them responsible for any thing beyond their treatment
