Case in the clinic

A grandmother is sitting in the corridor of the clinic.
A woman in a white coat passes by – not much younger than that grandmother. He passed by and then came back:
Hi to you! What did you come with? I saw you here yesterday.
The old lady extends a leaflet, right? He says:
I am in the seventh room. I stayed here yesterday and it was closed all the time. I sit here today.
The woman in the white coat looks at this poster:
You are in the 507 office. This is 207. Go to the elevator. I will accompany you. It is on the fifth floor.
have gone.
Just very attentive. I just passed by.
