The restaurant protects theifs

My phone got ****** on Sunday, and its last location according to Find My Iphone was at PLTFRM, and when I gave them a call on Monday, stating that I would like to see a footage to see who exactly stole my phone. The manager said that he would need a court interdict. I am not sure if his aware how long that takes and the emotional drain that comes with it. I explained to him that, I have communicated with the police and they said I can just ask to see the footage as I might know the person, because court interdicts take a very long time and once I get one, the footage might have been long deleted by the restaurant. I am very disheartened because I only asked for footage to locate my phone. Which is a new phone by the way. I highly wouldn't recommend this place. They protect *****'s.
