body: Today I was leaving a large commercial building (~15 stories) and walked straight into the glass surrounding a revolving door, thinking that the opening was not so narrow. 
  
  
  I went to the security desk and asked to use the bathroom to clean myself up. The person I talked to gave me some bandages and let me use the bathroom to clean the blood off my face. Another security guard then took down my phone number, email, name, and asked for an ID. Why did they take this info down? Are they going to contact me?
