I usually respond, "I'm sorry. I didn't feel the lead for that."
Then there was the guy who kept leading back ochos and trying to lead me out to the cross, but he wasn't changing back to parallel, so he kept trying to lead it when I was on the wrong foot. When he finally did it correctly, he said, "There you go!" :|
What do you mean by that?
I usually exit ochos using the cross in cross system walking.
