Here's an exchange I find more and more common at drive-through windows:
Distorted Voice Through Crackly Speaker: Hi, welcome to ____. Would you like to try one of our ____ meals? It's only $___.
Me: No thanks, I'd like a...
DVTCS: Go ahead with your order when you're ready.
Me: I'd like a _____ with...
DVTCS: (Interrupts) Would that be all?
Me: No. I'd also like a ______ and I need 2...
DVCTS: (Interrupts again) Anything else?
Me: Yes! I would also like a _____ blank and that's it!
DVTCS: Would you like fries or a drink with that?
Me: No. (Grits teeth) Just the ____, the ____ and the ____.
DVTCS: Thank you your total comes to $5.** (unintelligible). Please pull around.
Me: I'm sorry, how much was that? I couldn't hear it.
Me: (Mumble to myself, "Ah, forget it. She can tell me the total at the window.")
Fast food places are frustrating in this way. Either the suggest sell you and won't let you get your order out the way you want it, or they don't let you finish placing your order. The speakers at those places are so lousy you can't understand half of what they say.
