Where did the conversation most probably take place?

W: Please, please, can you help me? I seem to have lost my handbag.
M: Calm down, Madam. Well, I’ll have to fill out this report for you. What color is it, Madam?
W: Well, it is a white one.
M: How big is it?
W: Mm, I guess it’ s about one foot long and seven inches tall.
M: One foot long and seven inches tall. What’ s in the bag, Madam?
W: There is a wallet, two keys, and a letter.
M: And where did you leave it?
W: I am sure I left it in the coffee shop on the 5th floor.
M: Don’t worry, Madam. I am sure we can find it. Now could you give me your name, your address and telephone number?
