Cindy sees this one regularly in Southern California. Here is her explanation, of which I approve: "Maybe they have creditors after them who want them to pay up, or unsatisfied customers who they've treated poorly or disgruntled employees who they haven't paid in ages, and they're pretending not to be there just to avoid all of them. After all, if they've "moved", all these people after them won't think to look for them at their actual place of business, right?"
I don't usually post the following: newspaper headlines, personal email, craigslist postings, unprofessional websites. I also tend to not crosspost things from other blogs, since I have so much unique material waiting for me to get to it.
Things I see a lot: silica gel "do not eat"; hair dryer labels; inside the bus "do not drill"; Wal-mart sign about IDs; coffee machine with "2" cup sizes; employees must "wash hands".
