I would understand if they actually dressed up to look more homeless are struggling to get food but if you're wearing fresh clothes, sneakers and your hair styled, of course no ones going to give you their food they've worked for.
I felt sorry for the homeless guy and it's heartwarming to see that he would give another person food although he's also in a tough time.
I don't mean to sound insensitive, I just found that video to be quite try-hard and I don't it was executed well.
