No, its wonderful with a stranger. There aren't any awful niceties that you feel you have to be obliged by! I can pull when sober or drunk, but when I'm drunk I'm more likely to do the approaching, and get the guys that I want. My ONS (singular) is now my boyfriend, and we've been together nearly 2 years now, so it's not always awful and terrible. I was drunk when I met him and was fed up with meeting guys and going for their personality and spending time getting to know them first, only to realise I was attracted to their mind, and usually just saw them as friends... so I went to a party and pin pointed who I thought was a "stereotypically hot guy" on purpose, and took him home... and well... 2 years later and I've never regretted it!
Sorry for the rant.
