You still get hit with fees at the door in my experience. Considering most venues bigger than a bar are owned by livenation which is the same company as Ticketmaster…
Last couple times I went this year, it was a $5 fee at the box office, which was still considerably less than the $18 in fees online (for a $35 ticket). After I paid, they asked for my number and texted me a Ticketmaster link.
