. "Barring a disability, they’ve made the calculated decision that the performance did not merit their standing. Which is fine, but the entitlement in saying those who sit should dictate it for the rest of the audience is laughable."
And if the person does have a disability, then what?
Any person who buys a ticket to see a show seated is "entitled" to see the entire show seated--- and that includes the curtain call.
And as far as dictating what others must do, it is those who stand who are dictating to those behind them what they must do if they wish to see the curtain call. If everyone sat during the curtain calls, everyone would see them. But if some people stand, and others don't want to, then only some people see them.
So tell me, who are the ones displaying entitlement?
