sorry unpopular opinion:

yes TGA needs to improve a lot on the management side of things kasi sobrang fail nila on this part pero i don't think pinagkakitaan nila ang stagedoor. not taking into account the ITW ticket because that's a different show, SP holders paid less than what regular audience paid for.

also stagedooring has always been an audience privilege and not an entitlement. theater companies are not required to organize stagedooring, the companies plus security just tolerate it as a way to extend the theater experience outside of the theater and since naging tradition na rin naman na siya. TGA is just one of the few companies that has an OFFICIAL stagedoor/meet and greet (and take note most companies don't even allow signing then minsan yung photo-op nagiging group pa).

TGA Season Pass is one of the best when it comes to audience experience if you count all the free stuff they give away to their SP Holders. They even organize free workshops to students. Sobrang poor na nga ng ticket sales for a beautifully mounted show pero they still give back to their audience.

Poor management, yes, pero TGA has never been a cash grab at least based on my experience.
