In reply to Derry:
I was doing the Voies des Dalles on Le Pouce, semi hanging belay on a single mega resin bolt.
My feet were on a narrow ledge, but I was leaning out to keep an eye on my leader.
French Guide arrives, cows tail and krab at the ready, and I was just figuring if there was enough room on the bolt for him to clip into, when no, before I could move, (my memory is of blurred hands), he'd unclipped me from the belay with one hand while simultaneously clipping the bolt, then he reclipped me to his krab, which wasn't a screwgate.
Then he's hanging like me, he didn't have a ledge, bringing up two clients on separate ropes. I was working out that if the worst came to the worst, (my leader, me, the clients, maybe even him if they all fell at the same time, there could be five people hanging off that krab.
I can see the logic, as I was able to leave the stance pretty quickly, but when I looked it up in my Blackshaw's, there was no mention of this technique.
Then there was the guide who started front pointing up my rucksack on my back just at the foot of the chimney on the summit block on the Plan.
He didn't manage to complete the move, I have never used such filthy language in the Alps. I sincerely hoped he understood it.
