I Have a Bone to Pick With KFC

Why is it when you go to KFC and your order needs more cooking time, the cashier always says, "Your (insert order here) will be ready in about 4 minutes?" It is NEVER ready in 4 minutes. Try 8 to 10 minutes. I would rather they be truthful and tell me how long my order will REALLY be ready than for them to lie to me. It's not the wait that I'm complaining about; it's being mislead and/or deceived.
