more wonders of capitalism

taco bell has a sign on the wall saying if ur unhappy about ur service, or don't love the food, you can have a refund or replacement, your call.

borders let someone return a book with no receipt two years after purchase.

why does this not happen w/ a command economy? under capitalism, making customers happy helps win business from competitors. under a command economy, there are no competitors, so there's no reason to do it. and also, it's wealth redistribution (those who ask for more, get more) by some method other than the commander's Grand Plan, so philosophically an anathema to socialists.
