At a USPSA level II match, I ran into the non-standard language. I thought I would have some fun.
"Do you understand the course of fire?"
Nope, I thought I would try a practice run first to figure it out then do it again. Thanks for asking though.
"you...you can't do that..."
"why not?"
"only 1 run per shooter."
"Then why did you ask me?" pat on the arm. "Just kidding. But you should not ask questions you don't want an answer to. You are not using the standard range commands for USPSA and it confused me. Come on, let's go."
