That's pretty pathetic Charley! If you're like me, it was probably the demanding attitude about giving up your campsite that set you off
For myself, I haven't generally had many guided trips, except for a couple times, on foreign trips. Last September in Peru, my guide, who was actually quite competent otherwise, got absolutely s*** faced drunk on night 4 of our 10 day trek. It would've been a long way out on our own at that point, but I seriously thought there was no way he'd be able to function the next day, and that we might be stuck there another day while he sobered up. We had a 16,000' pass to cross: I wouldn't even be able to tie my shoes the next day if I were that drunk! He kept pleading pathetically for more money to buy beer (there was a tiny store near where we were camped that sold it). I can't begin to describe how mad I was! I got busy studying my map and contemplating escape routes. But he got up the next day and did his job, somewhat abashedly. He actually did quite well, though you could tell he was suffering
I have a suspicion this wasn't "crazy" behavior, but rather, "normal" behavior for a certain percentage of Peruvian guides: there is a reason that store sold beer
