What Ever Happend To "The Customer's Always Right"?

Been through a fast food drive through lately?
You pull up, give your order, they repeat it back to you, and you pick it up at the window. 
Sounds easy enough right? 
Until you get it home and realize you got nothing you ordered, no condiments at all, not even a napkin. and your just supposed to shut up and eat it.  Yet if I were to pull up to a drive through and say to them:
"Just throw something in a bag and give me a price because I never get what I order anyway"
they'd take offence.
I was in a local corner store just last week and asked the person behind the counter why an item was priced so high when I'd seen it at another store for a lower price and the response I got was:
"Well you don't have to buy it"
YOU BET YOUR SWEET ASS I don't have to buy it, and I didn't either.  I've not set foot in that store since nor do I ever intend to in the future.
And don't you just love it when you pull into your local convenience store at 5:30am for coffee on your way to work  only to find there is none and then you see one of the two attendants in the store standing outside on a smoke break drinking a cup?
What the hell is happening here?
How come no one cares what the customer thinks anymore?  And how come consumers don't demand to know why?  Have we all just accepted the fact that the drive through attendant is just to lazy to care, or even want to try to get our orders right?
As hard as jobs are to find how come those who are lucky enough to have one don't give a rats ass if they do them right or not?  And how come they still get to work there with that kind of attitude to begin with?
Maybe if consumers just once demanded to be treated the way they should be and refuse to patronize places that don't provide good service they wouldn't have to waste time checking to make sure they got what they ordered. 
You wouldn't go to a doctor who didn't give a shit about you or his job, but you'll accept that kind of attitude everyplace else?
Have we become so politicaly correct that nowadays we just accept what ever kind of service we get good or bad and like it?  when did the motto go from:
"The customer is always right"
To:
"If you don't like it, you can go someplace else"??
