They're certainly best friend because the dog is usually just chilling around him whenever I see them. I paid attention to them for some time without being creepy but I couldn't draw it from memory hehe. At home, I tried to reenact the scene by asking my friend to pose lol.  
                           
Hmm some owners clean up, others don't. I guess that's just expected that there are responsible and irresponsible people around us.        
                           
Thank you Ms Delish :).
