Of course you will never find anyone who exactly match the situation of anyone else. That is not a reasonable criteria. Gatsby is more similar to Tony in that both had an exhausted donor, and had a lot of beard grafts implanted.
Overall, I think dr Sethi suggested that he could help Tony, but I'm not sure if he meant that he could create a satisfactory results in one go. I doubt that he did promise that. I am not an expert at his level at all, but I would assume that a case such a Tony's would always take several rounds - just like Gatsby's has done.
If this is indeed the case, then I think the lynch mob mentality is a bit premature. Let's at the very least wait and see what Dr Sethi and Tony agree to. Furthermore, I know that Dr Sethi has had to postpone a couple of times, but let's be fair - he has not postponed indefinitely. Rather, this postponement I believe was merely one day. I suggest to keep a level head and put the pitchforks away until they have had a chance to sort this out.
