Customer, Interrupted

(I am at a popular burger chain. The lineup to give orders is fairly long, and while I am waiting I keep rehearsing my order in my head so that I can rattle it off fairly quickly.)

Employee: “What would you like?”

Me: “I’d like a [Burger] with—”

Employee: *interrupting* “Would you like fries with that?”

Me: “Yes, please. I’d like—”

Employee: “What size?”

Me: “Large, and—”

Employee: “What would you like to drink?”

Me: “Just water, please, and—”

Employee: “Is that for here or to go?”

Me: *sigh* “To go.”
