A McDonald's in West Houston is taking community outreach into it's own hands and starting with image. They've put up a sign that warns, "PULL YOUR PANTS UP, or Don't Come In!!! Try to have some decency and respect for others. No one wants to see your underwear." I've heard the same thing from my mom, but when you see somebody with their ass cheeks hanging out in the subway, you see why it's not a good look.
Elders seem to think that it's a good idea, but younger customers aren't too happy about being told what to wear and when. Maybe if they don't pull their pants up, they can at least improve their diet.
