Unless they knowingly over served him and were worried about that problem, it seems odd that anyone would want to have someone in their establishment in that condition. There is nothing good that could come of it. If he's passed out drunk chances are good that he's going to PUKE at some point and possibly cause a bunch of othe problems. Worse case if he's drank alot in short period of time, he could die. If he wasn't drunk and was unconsious, that's probably an even bigger problem.
You did well by calling 911, err on the side of saving his life.
