I was forcibly blocked from accessing my locker by 2 dudes obnoxiously chatting away right in front of my locker at the gym...

After working out at the gym yesterday there were 2 guys talking to each other, with my locker in-between both of them. They were chatting it up as though their conversation was the most important event of the day. I didn't want to get dragged into their conversation, so I went back into the gym and walked around. I came back into the locker room and there they were still talking with one sitting on the bench and the other pacing back and forth as he was speaking with overly animated hand movements. It was a full 15 minutes until they finally left and I was able to access my locker to leave.
