Until Mayor Billionsberg showed his true-green(back) colors with Occupy Wall Street, I pretty much tuned out all the complaints that he had become the city’s nanny. But the other day we were in a crap-ass cafe for a quick lunch that was arriving slowly when I noticed how many signs are now required on the wall. Of course there is the once-brilliant, now-muddled choking poster. And the No Smoking warning. And the “pregnant women who drink ate so stupid they must be shamed.” But there was also a big scary poster on the risks of food allergies. A notice on the location of the CPR kit. Etc. By the time our dispiriting food arrived, I actually started to worry when a couple came in with two little kids, one of whom they strapped into the grimy communal highchair. Had no one warned them what might happen if the chair tipped over or the strap was too tight or the tray table had peanuts on it? It all reminds me of that old Joe Jackson song about how “everything gives you cancer” — fear is immobilizing. How did we ever eat out before we were warned? On the plus side, though: If a pregnant woman had too many margaritas and her companion started choking her, everyone would know just what to do. Start smoking.
