If I invited you over to my house, and you arrived at the specified time, and you knew I was home, but I made you wait on my doorstep for 10 minutes you'd probably be pissed, right? You guys seem to think it's totally fine to leave a guest waiting on the doorstep for 10 minutes. I'm shocked. I mean, would you even wait 10 minutes, or would you just leave because I wasn't letting you in? These boards always say you wouldn't invite people to a dinner party then charge them for drinks, or not have enough seats, or server yourself something different than the rest of your guests...how is this different?! Apparently it's OK with all of you to invite people to a dinner party, then make then knowingly wait 10 minutes on your doorstep. Wow.
