My favorite was when I asked two girls if I could work in with them on a tricep machine.
No adjustments to the machine except for moving a pin on the weight stack, it’s not like loading/unloading a free bench or something.
Their response?
“No, we’re in a hurry.”
Oh excuuuuuuse meeeee! Gosh, it’s sure lucky that nobody else is “in a hurry” eithe, huh? Like most folks I want to do my workout in a timely fashion and head out. Pretty please learn a little bit of gym etiquette and realize that it’s not your personal machine to monopolize. If we all cooperate then we all get done faster and you don’t have to deal with my “WTF” look.
