You think cops live on the wild side? You haven't really seen the seamy underbelly of the city until you've shadowed one of the city's public-health inspectors as they check out whether restaurants, tattoo parlors and swimming pools are meeting required safety standards or investigate the source of a neighborhood noise complaint. You must apply in advance (and pass a background check if you're interested in child-care facilities) and there's no guarantee what kind of inspection you may be in for, but the agency tries to accommodate the curious public. Just be sure to follow the rules, like the one about no free treats from restaurant owners.
