Escape from the coffee house

Today you were the last one in the coffee shop, as all the cleaning remained at you. But here's a surprise, you have lost the key to the front door. How now here you will choose? Cheer up, there is always a way out, and we'll start looking for that same hour. Collect all that can somehow be useful to you, and will look at different options for emergency exits. We will not stay here for nothing!
