Weekly Prompt Writing

I actually went to the meeting last night, so I have a prompt this week!

I whistled as I strolled by the many shops of downtown. It was a glorious sunny day, despite the chill, and I was in a determinedly happy mood. My sister would be coming over tonight and I thought I'd order something special, something we'd both loved in our childhood.
I walked into the pizza place and waited in line to place my order. "One large Hawaiian pizza with extra pineapple and anchovies, please," I said.
The cashier paled a little—perhaps at my topping selection?—and told me to wait there. I did so, and in a couple of minutes she came back, looking even paler. Without a word she gestured me to follow her, glancing around with suspicion. I followed her to the back of the shop, then down a dank staircase and into a danker basement. Before I could ask what I was doing down here, a voice slithered toward my ear in the darkness.
"So. You've come at last."
I cleared my throat. "Look, if you don't like my pizza choices, I respect that, but it hardly necessitates kidnapping me—"
"Enough joking, Kramer. Did you bring the money?"
"I don't know who Kramer is," I told the darkness, "but yeah, I'm prepared to pay for my pizza." I realized that the cashier had disappeared back up the stairs.
"Please," said the voice, "cease the dramatics. It's a simple transaction. I provide the goods, you provide the collateral."
"Right. So where's the pizza?"
The voice let out a long-suffering sigh, then yelled at the top of its invisible lungs. Two feet scampered down the stairs.
"Yes, sir?"
"This man is buying a pizza, Jules. BUYING A PIZZA. You've just given away our front to a mere civilian. I'll not have this kind of behavior. You're fired. Now, for the sake of my business dealings, I'm afraid I'll have to hold both of you hostage until the real Kramer shows up."
