I drink beer while truing wheels, so I have no problem with that. The loose spokes, however, are a problem. Go back and have him retension the wheel. He should do this for free and very quickly --two days max.
If he won't do it for free, or won't do it well, raise a bit of hell. Get him to reimburse whatever he charged you for labor, then go to another shop and have them retension the thing. You do not need to rebuild the wheel yet, but getting proper tension on the spokes is imperative. Do it ASAP.
The guy is on tour in Patagonia. It sounds like he's pretty far from the original shop, and even if he wasn't, I'm not sure raising a stink and demanding refunds is going to get you very far at some backwoods shop.
