Whose Convenience?

Why don't they just call it what it is?  It's a fee to purchase a ticket.  It's not convenient for me to spend an additional $2.95 per ticket.  WNYC's The Green Space is not the first venue to label it a "convenience charge". 

I just purchased two tickets to see the Jayhawks at the Green Space, which I'm excited about.  I haven't been there. I haven't see the Jayhawks in years.  I don't mind a $3 fee. It's definitely within reason, but I hate it being disguised.  Tell me what it is. 

That being said, there are still tickets available for the Sept 19th show and the "ticket fee" of $20 includes a glass of wine or beer:  very civil.
