Changing a handle from left to right on a spinning reel takes less than fifteen seconds.I saw a high school kid holding a spincasting reel upside down and reeling backwards the other day. I think the problem is that there aren't enough mentors stepping in to lead 'em in the right direction
I have proactively switched handles for people and have experienced that mind blown look. As much as its fun to laugh and joke when i see it, I wouldn't want anyone else to leave me hanging like that.
