I just ran into a random guy out in the middle of nowhere and he yelled "Hey there you are, pay up!" I said, "Who are you?" And he said "Don't you remember, we got drunk and trashed the temple together a few nights ago." That's all the interaction you could have with this guy but still pretty cool.
It is a good questline, you may even get a random encounter later on related to it.
One little issue I'm having right now is that I decided to try a female character and he hasn't appeared for her at all, she's been everywhere looking for him but no joy, all my male chars met him though.
Unfortunately I missed a lot of the quest thanks to previous encounters with

giants and hagravens. The rest went pretty much like it would in real life by paying off any damages I do in a blackout stupor. I ran into that Argonian after the fact. I persuaded him down to 750 gold for the hat.
