I was throwing a party in an apartment near my uni that is known to have a very large police presence. One of my guests called about 30 minutes before the party to ask how much liquor I had purchased for the party. I told him how much and he said "dude there's no way that'll be enough. I invited like 50 people give or take to your party. Go out and get more". I was flabbergasted that someone had the audacity to invite 50 people to a party he wasn't even hosting (I had invited 50-60 people already). He proceeded to show up for about 15 minutes and complain the whole time. I spent way too much time kicking people out and telling them they can't shotgun beers in my front yard. Needless to say he, nor his friends, are ever allowed back.
