Oh man, I am a teddy bear with people that are reasonable, make sense, and ask the right questions.
But for people that complains that something is not exactly as the old stuff, I have not time for. Here, let me give you a better example.
Have you ever worked with someone that came from a different company, and everytime you have a neeting, this person brings out that that was not the way we did it in company x,y,z?
What do you do with him? Let him ramble on, or you tell him, listen buddy you are not at x,y,z anymore, you are at a,b,c, so if you don't like it, move on.
Or you are too shy and timid to tell them how you feel? Sorry for you. Maybe you need to man up and express your true feelings. There is nothing wrong with that.
By the way, you do know that most people treat strangers better, more civil and with more courtesy than their own family? Not me buddy, I let you guys have it, in person, and here. But come home as sweet as candy! LOL. Learn my friend, man up!
