A great many venues do not have ticket windows/box offices for buying tickets in advance; you buy in advance online or you try your luck at the door if there are any remaining, where you'll probably still have to pay some kind of extra fee....
Ticketmaster and other enemies of artists...
Did you notice that ticketmaster sometimes overcharging tickets more than twice already? Ticketmaster isn't the most crooked vendor! There are a lot more charging "conviniences" BRUTALLY to the point of 3...4x the original price of a ticket.
Here was my solution. Just took a ride to the box office, pulled out cash and purchased tickets YAY for original price leaving those crooks unpaid. $44 vs. 75+convinience fee at ticketmaster!
I'm sure that artists don't get enough bookings because of those crooks.
Do same as I do so they will go a lot slower!
