lost phone coincidence

Hello, This happened in 9th of August, 2014. I studied all night for my exam, then left home early to catch my exam. I was waiting in the bus stop for my bus, when this beggar came and asked for money saying he needed food. I usually either say no to these kinds of things or just neglect them. But that morning I felt like helping to that dude, so I went and bought a bagel for him, he thanked me, while eating the bagel. He sat next to me and we had a little chat about his daily problems, then my bus arrived and I left for my school. I took the exam. After the exam I felt kind of sloppy due to not getting any sleep last night. I went to the bus stop to wait for my bus to return to home. While at the bus stop, I made a phone call. After the call, I accidently put my phone to the bus stop instead of my pocket. Then my bus arrived and I left forgetting my phone on the bus stop. When I got home I realized that I didnt have my phone with me but my home mate opened the door talking to a person who found my phone and asked me to come and grab the phone. So, we decided to meet at a place and I left home. When I got to the place we decided, I saw the beggar I bought a bagel in the morning. I was quite shocked, he seemed so as well. Then he said he wouldn't return the phone to its owner if I didnt bought him that bagel in the morning. He added he felt like helping someone because of the morning event. The places where I met this beggar and where I left my phone is have like 15km between them.
