We borrow a lot of slang from the english.
My grandmother is/was from Birmingham so I understand where it comes from with me, but I think a lot of Americans [since there are a fair share of KS] do carry some form of anglo influence. Plus a lot of Americans tend to be obsessed with the Royal Family for some reason.
These are all so true. But why do we use so many of these instead of just saying flat out what we mean?
Direct conflict in public = Making a scene. Plus if we say what we mean it becomes I don't know tacky after a while. Like when I was at T-Mobile earlier today at there was like 2 people working and it took almost 25 minutes for me to get seen and the woman in front of me said "I'm sorry for the hold up..." And I was like "It's fine.." It actually wasn't it was annoying, but I wasn't going to say: "This is irritating. I've been here for 30 minutes... but It's not your fault, but I'm still pissed off..." In those instances a "It's fine" is better than saying what you mean. lol
But its like the "do you need anything"... Its a vain gesture that both parties know is just for good manners and means nothing. If the other person says "Yes. Could you go to the store and pick me up a 12 pack of Pepsi..." it would likely piss the first person off.
