Eek! What a scary sign! We've got apostrophe catastrophes, random and stupid capitalization, and what I strongly believe is a homophone error. I suppose he could have meant personnel belongings here, but it's far more typical to see personal belongings in this context...and judging by all the other mistakes this person's made, I'm going to figure that the personnel/personal thing is likely also an error.
Thanks to KIM for spotting this one!
