My climbing partner was just about to set off on a route at my local climbing centre yesterday, when I happened to glance across at someone belaying their partner up a route further along the wall, and thought something doesn't look right. After thinking about it I realised the braking end of the rope was in her hand in 'feed' position above the Gri Gri, but holding the rope with the hand oriented thumb upwards. I took a closer look, then went to reception (as there were no 'wall-walkers' in the vicinity), explained what I has seen, and said it would be a good idea for them to check her belaying and have a word with her, as her hand position would prevent her putting the rope into the locked off position.
I didn't see anyone talk to her about this, and she continued to belay the same way for the whole evening. Added to this the way she was feeding the rope meant she quite often didn't have a hand on the braking rope, or sometimes just held it in a couple of fingers.
Later in the evening my partner pointed out she was currently holding her partner on the rope with both hands on the live end of the rope, and the belay device below her hands. I asked one of the staff 'is no-one going to have a word with her about her belaying technique'? She had stopped just holding the live end by then, but was still belaying with the rope feeding out upwards with her hand in what seemed the wrong position to lock off.
He went over and and asked her to belay with her hand the right way up, and the rope oriented correctly. Her response apparently was 'its a Gri Gri'. She did as she was asked for that climb but then soon switched back again, and was not challenged about this.
The member of staff explained to me quietly that it was probably to do with the way some people belay on the continent (I think she was Spanish).
I realise I could have had a word with her myself, but I don't have tons of experience with the Gri Gri, and figured it could be a different type of device, or maybe there was a school of thought where that kind of belaying is seen as ok. They gave the impression of a group who had been climbing for a while - so maybe they knew something about self locking devices that I didn't? Plus I got the impression that one of the males in the group probably thought I was staring at her rather than looking at the way she was belaying!
So my questions are:
* Is it common in Spain (and elsewhere on the continent maybe) to belay in this way with the rope feeding out of the Gri Gri upwards but the braking hand gripping the rope in the unlocked position, above the belay device, with the rope in the hand thumb upwards?
* Is there any way this could be considered a safe way of belaying? Her comment 'its a Gri Gri' suggests she thought the device was failsafe and maybe it is, more or less, in normal circumstances without eg rope drag or other factors preventing a shock-load coming on the device. It seems like holding the rope in a position where you can't rotate your wrist to lock it off (and so relying only on the auto lock of the Gri Gri) does not seem a safe enough way to belay, particularly in a climbing centre.
* Should the wall staff be taking this more seriously and talking to her after I first mentioned it, rather than just letting her carry on for the whole evening doing the same thing until I mentioned it a second time? And even then not paying attention to what she was doing after they had told her, to the extent that she just resumed doing it? It seems like a wall should really be enforcing fail-safe belaying practices, not allowing people to belay badly just because they are continental and 'that's how some of them do it out there'.
* Shouldn't a Climbing Centre be noticing this quickly and having a word themselves rather than a customer having to highlight it to them more than once? I can understand them not noticing if it was an isolated incident (we all make the odd mistake), but she was belaying like this for the whole evening.
