Pet Peeves At Their Best

Ok so I have this pet peeve and I've had it for a long time, but lately, with all the meetings I do and all the group discussions I'm in, it seems to be rearing its ugly head. I can't stand it when people ask questions at unrealistic and inappropriate times. For example.... If I'm in a training and the trainer says, "Yeah, we're gonna have to run a little late since we didn't get to everything I wanted to cover." I don't want to hear every one's personal dilemmas with that. Here's what normally happens: A trainer will announce that to the group of 30 or whatever and inevitably, there's that one person that raises their hand and wastes my time by asking, "Well, I was gonna go to lunch with a friend and I have to meet the plumber at 5. Can I go a little early anyways?" I DON"T WANT TO HEAR YOUR PERSONAL QUESTIONS!!!!! Wait until it's break time and ask the trainer then! I don't care that you have a plumber coming to your house and I"m sure none of the other 29 people in the room do either. Like, don't people think to themselves first if this is an appropriate time to ask specific questions that only relate to themselves? I guess not cause this happens all the time and I just want to scream, "ASK AT A BETTER TIME!"
