These disenfranchised homeless people aren't going away as much as many of us would love for them to cease to exist. Truthfully, until something changes this grossness is only going to get worse. Soon, they will be shitting in the isles of your grocery store. So, offer up a solution. It's easy to identify the problem. Fixing it is another ball of wax...or in this case pile of shit.
Imagine this. You have no home and thus no toilet. You think fine, I'll just ask to use the restroom at the supermarket. Too bad, it is locked. The sign says customers only...ask for key. Your not a customer...you can't afford to buy anything and no matter how desperately you plead, you won't get the desperately needed key to poop into a flush-able toilet like most other humans. Oh, and by the way, the key is not for you, it is for your indigent parents who are begging for you because you are only a kid. Dad, mom...please! Too late, you just shit all over the floor of the produce isle. Yuck!
Fix this!
