I want a dozen crabs... Pete!?

Anna: Hello! Washington, D.C. sits on the Potomac River. This river is important to the history and culture of the city. Today, I am at an outdoor seafood market near the Potomac River. Some say it is the oldest outdoor seafood market in the United States! I am here to buy seafood. Let’s see what they have!
Excuse me. Can you help me?
Pete: Sure! What do you need?
Anna: Pete!
Pete: Anna!
Anna: What are you doing here?
Pete: I work here. You know, it’s not easy to be a writer.
Anna: Yeah, I heard that. Sorry.
Pete: But this job is great. I work outside by the river. And I can eat all the free seafood I want!
Anna: That is great, Pete. In fact, I am here to buy some seafood for my dinner party.
Pete: You came to the right place. They have the freshest seafood in town. How much money can you spend?
Anna: I can only spend $50.
Pete: Okay. What do you want?
Anna: First, I want to buy some shrimp.
Pete: Sure thing. Follow me. How much shrimp do you want?
Anna: How much do I need for five people?
Pete: (yells to co-worker) Give her a pound of shrimp!
Anna: Ok, now I want to buy some crabs.
Pete: The crabs here are delicious! They are the best because they come from the nearby Chesapeake Bay! Walk this way.
How many crabs do you want?
Anna: I want a dozen crabs.
Pete: You should get the larger crabs. They have the most meat.
Anna: Then I want a dozen large crabs, please!
Pete: Is that everything you need?
Anna: Let’s see ... I have shrimp and crabs. And a friend is bringing a salad and many ears of corn-on-the-cob.
Pete: Is that all the seafood that you need?
Anna: Yes.
Pete: That’ll be $49.95. Cash or credit?
Anna: Credit, please.
Pete: Anna, you love to eat seafood. Did you grow up on the water?
Anna: No, I didn’t. But I love the water. And I love being on the water.
Pete: You know how to sail?
Anna: Well ... this afternoon I am going on a boat.
Pete: You are full of surprises. What kind of boat? Is it a motorboat or a sailboat?
Anna: It’s a special boat, Pete. Well, thanks for your help. See you later!
Pete: See you, Anna! Wow, Anna’s a sailor! Who knew?
Anna: Yes, rivers are important to the history and culture of Washington, D.C. And now I am part of this city’s interesting waterfront culture. Until next time!
