Old folks on the loose

I work near a theatre. Thats not a very exciting fact really, and it doesn't cause me any issues in my day to day life. UNTIL>.........I come out of work to see hordes of old people waiting at my bus stop! Honestly I don't think I've seen that many old people in the same place ever! I didn't manage to get a photo of the actual event but heres a scarily accurate image....
