I usually unclip my left foot first, lean slightly that direction with my foot on the ground, I then come to a complete stop and then unclip my right foot.

For some reason I had gotten my left foot out and on the ground but my right foot just wouldn't unclip and I just (in slow motion) fell to the right...but I had come to a complete stop already and had my left foot firmly on the ground. I guess I just didn't lean the bike far enough to the left. Ya live, ya learn. I'm sure glad I can share on here, none of my friends ride so they just don't get it.
