We've all had some leaks, and some embarrasing moment, my worst was the clip to the bag breaking and spilling down my leg at work, I survived though, that was 20+ years ago.
I think that is why you get a new clip, I use them now.
I keep a little squeeze container of Karaya powder in my car and desk, if I had a purse, it would be there. when I am away and have a leak I go into the rest room and lift the edge and squirt the powder in. I seals it up until I get home.
