Don Draper and friends are well-documented fans of the midday cocktail. But even in 2013, drinking at work isn’t entirely out of the question. A growing number of companies are offering booze at the office, whether via fancy vending machines, kegerators or well-stocked fridges. Employers say this perk is an effective way to lure talent and encourage bonding, while avoiding a stuffy, corporate atmosphere. Plus, at many companies where the work day often extends into happy hour, providing free alcohol keeps employees at their desks even longer. But there are some drawbacks- for instance, people who don’t drink may feel excluded from the camaraderie of in-office boozing, and there is some concern that drinking on the job could lead to sexual harassment, rape or drunk driving. It probably also leads to an increase in butt-photocopying.
