Lunchtime is work-time at many offices. If you're not hunched over your keyboard, typing while eating, you're probably at a lunch meeting, schmoozing while eating. If you're stuck planning one of these work-and-eat sessions, you're also in charge of making sure it's a good use of everyone's time. So how can you do three things at once?
Bad table manners are like any lapse in etiquette – when the problem is coming from someone else, it's immediately apparent, but if you're the offender, you probably don't even realize it's an issue. (This explains such mysteries as why there are still people who belch in public or trim their nails on public transit.) If you are an unseemly eater, you could be damaging your career and not even know it.
