You were "waiting" for the hazard of dislodging to cease- if another group chooses to expose themselves to that hazard and pass by you, although it isn't the most courteous action, it is to be expected on Standard Route.
Your ongoing cotton undergarment shtick is simply the most misguided ignorant "technique" I've ever heard.
If the guide can not gave the example of courtesy...like you do...who will gave it. If I was waiting at the bottom it was to avoid the ice, but also to let the other climber to have a nice day and finish the route at there speed. Even if we start after the leader, if I was slow to place my screw on the steepest place, if I climb the pillar, I had to wait that the other party move to the top before leading the last pitch.
As you say that it is a misguided ignorant "technique" you
ever heard, we can explain why it is normal for you to pass an other team who was waiting. I climbed la pomme d'or and used to camp a week in the coldest months of the year each years...just for fun...solo. I spend a lot of days outside, as I said, I study how animal conserve there energy in my master degree and I test different technique to adopt cotton t-shirt as a very effective method to stay dry.
What I am saying, is that there are guide and Guide
. Insulting some one of ignorant when you never heard and test the technique before... it is guide.
