Getting hammered on the job is a no-no, especially where people's lives are in your hands. My only experience has been as a fishing guide and a backpacking club advisor, but I took my duties and job very seriously and was very glad to have every last brain cell firing when the inevitable accidents happen. I was incredulous before she marched into our site, Bobito, it was obvious what kind of state they were in. If one of those kids had been injured or the usual lovely unpredicted Sierra weather event took place, they would have been in dire straits. A little misery and altitude sickness got them off lucky. I would have seen red with your Peruvian guide. Glad it worked out.
