The Wisdom of Back Packers - pass the dooby to the left hand side

So I managed to finally extricate myself from Emery and Indira's spare room and am back on the road again, after a weekend in Michocan and a day in Mexico City... and immediately I am reminded of why I love hanging out with backpackers.
After landing in Puerto Escondido at 6 in the morning, with an eight hour overnight bus ride under my belt I managed to find my way to a youf hostel, and collapse in to bed. later in the day as I am sitting on the terrace, reading my book and enjoying the breeze I am joined by a multinational crew of young gentleman. The hot topic is dooby passing etiquette, with an American holding forth on his opinion -

Well I always pass to the left, but you know back home, if you pass it around it never comes back. But, yeah, here, usually I pass to the left, because you now, its just habit. Unless, you know, the person who rolled it is sitting on the right, in that case I would pass to the right, but usually, yeah, its to the left.

His German and Australian friend, nod at this sage advice and then give their opinion.

Am I too old and cynical for this crap ?
