Actually, there's another reason why they wouldn't. Over service. In many places, including Colorado, it is not legal to keep serving drinks to someone who is visibly intoxicated (and you don't go from appearing perfectly sober to "extremely intoxicated"). It puts a bar or other establishment at risk of serious fines, loss of license, etc. as well as liability for any injuries caused to third parties (and family members probably count). So they wouldn't have wanted anyone to see that he was that drunk because it would have been proof of illegality.
