This is really sad.
Throwing water on a poor guy like that when he is sleeping...Yeah, it may be funny to some, but I find it very sad and tasteless. These people maybe down on their luck, but show some decency guys. Sure, some may be lazy, or not wanan work, or drug addicts, or what have you, but Their suffering enough as it is for their mishaps in life. No need to add to it like that.
I don't wanna get in a argument here about wether they deserve it or not...The point here is you gotta treat people better then that, specially someone who hasent done anything to you...The poor guy was just trying to get some sleep and stay out of the cold. This really makes me sad.
