I'M LOST in NYC

Last summer my daughter and I were walking down a street in New York City in the Upper East Side and I needed an adaptor. It was essential for me, to recharge my mobile phone.
I: Excuse me, is there a shopping centre near here?
Man: Yes there is one. If you take the bus at the bus stop over there, and get off at the last stop, there is a very large shopping centre, where you can buy everything.
I: Thank you.

At the shopping center:
Shop assistant: Hello, how can I help you?
I: Hello, where can I buy an adaptor please?
Shop assistant: it’s a electrical shop, there’s one on the second floor called “Dixons.” take the stairs to the second floor.

My daughter is on the ground floor looking at fashion shops, but I’m lost. I can’t find the exit for the floor.
I: Is there an information point near here? I’m lost and my daughter is waiting for me at the ground floor maybe.
Shop assistant: Can I help you? Your daughter? Where is she? How she looks like?

I: She is a young lady, not very tall, with long blond hair and brown eyes. She has a little nose (like her mom, obviously!) a large mouth and she’s very thin. She was born in Italy, but now she lives in the United States....and she speaks English very well.
Shop assistant: Can you ask her by mobile phone?
I: No, my mobile phone is down but I can describe what she’s wearing:
I: She’s wearing a blue skirt, a white T-shirt and a black jacket. She’s wearing sunglasses by “dolce e gabbana” and she has got a red mini-bag. I’m desperate and I don’t know if she’s still waiting for me.

Shop assistant: Don’t worry, Sir; Now we call her with speakers.......what’s her name?
I: Her name is Marianna. Thank you very much.
