Splattered

Bin at the recycling centre. When I was taking this, one of the workers came over, frowning, and said, "Can I help you?"  
"No," I replied, "I'm just looking for a possible abstract photo. Is that okay?"
"I guess so."
Made me think of another blipper who's been questioned about taking photos in public places. 
Seriously, what's would I possibly be taking photos for that wouldn't be okay at a recycling centre?
