When I come to a stop, I clip out on the left (my right leg is stronger so that's the one that's always clipped in) and let it just dangle off the side of the bike as I start applying the brakes. Then I put weight on the right foot and bring myself off the saddle fully supported on the right leg as I drop to the ground and put the left foot down. Then I just crank my right leg back up and when it's time to go again it's already in the right position to give a good push on the pedals and give me some coasting time to clip in on the left.

In emergency situations I'm terrible. I rode Ft. Davis last weekend (a very serious hill climb for 11 miles) and at one point at a hill base I was so tired and wanted to rest, but my legs could not clip out. End result was a simply fell over onto my side at a standstill. My pride was hurt more than my body.
