Yeah. And let us add undisciplined. Put 'em on a leash. And quiet them down. Screaming, running, kids accelerate me from level headed and reasonable to the point of insanity in less time than a McDonald’s server.
Worse, if I become sufficiently annoyed I will explain my ‘PITA’ views regarding public behavior to you and your children. Just did it yesterday at our daughter’s wedding reception. Yes, my wife will elbow me. Or kick me in the shin. And it will hurt. But I will get my point across. And I will continue until such behavior is acceptably modified or I embarrass you enough that you pack up your unruly kids and leave in disgust. (Usually, as was the case yesterday, to the standing ovation of others present.)
Other PITA behavior that I share (without going back and quoting every single line):
The whole key thing mentioned by D_Odds: Mrs. Disguise, there is a reason why we have two sets of keys. Thou shalt not touch Lucy’s keys.
The whole customer service thing. For normal, everyday service, I behave in an acceptable civilized manner. Leave appropriate and sometimes even generous tips. And if I should get good or superior service, I go out of my way to bestow an appropriate complement. I talk to managers. I write letters. I make referrals. I become your marketing departments greatest ally.
What makes me a bigger PITA than anything else I do is this: If I get substandard performance I go out of my way to make certain that everyone knows about it. I talk to managers. I write letters. If possible I will drive customers away from your business. After I leave your establishment I will become your marketing departments worst nightmare. Anyone who gives me a 10 second window of opportunity will get a 10 minute ditribe on what a lousy experience I had with your business, and why I now do business with these other guys …
My wife, who is looking over my shoulder, suggests that I should mention that I go to McDonald’s (apparently) for the sole purpose of getting practice in the above. (They screw up my order 99% of the time, so I get lots of practice!) True to my word, Arctic Circle has only screwed up my order once in the last 4 years. Good service (they actually spend a few minutes training new hires), reasonable prices, and quick and efficient service. And you never even have to ask for napkins. 
And one last thing Mama suggests: When you are talking to me, Say What You Mean. If you are in any way ambiguous or phrase something that in a way that might in someway be interpreted in way that is clearly not what mean, I will purposely, intentionally and with great malice misinterpret what you say.
“Nobody doesn’t do that …” (and yes, I will interrupt you just to make my point …)
“Well, if ‘nobody doesn’t do that’ then, since a double negative = a positive then ‘somebody must do that’ so get to it!”
“Your order will be ready is just a sec …”
Second’s up. Where’s my food? What do you mean that’s not what you meant? Where’s your manager?
Yes. It all must be true 'cuz Mama says it’s true. And she will not enter a McDonald’s with me.
I am a Pain In The Ass.
Lucy
P.S.
I heard that. Get off my lawn.
