I'm glad things didn't turn out as serious as they could have. I would be hating those people too, since they knew you were coming. Since everyone else has addressed the issue of shots and what not, I'd just like to comment on one thing that hit upon a pet peeve of mine in your post.

The poodle continued to bark but was wagging his tail.
Now maybe you didn't mean for it to sound the way I took it, and if that's the case I'm sorry. It really irks me when I hear someone say "but he was wagging his tail" when they've been bitten or snapped at. A wagging tail does not equal a happy or friendly dog. The tail "language" has to be taken in context with the rest of the dog's body language, the position of his ears, the way he's holding his body, even the way he's holding his tail. I wish more people could read a dog's body language better.
