American workers have no problem funding their Starbucks addiction, but it wouldn't hurt if their employers met them halfway once in awhile. According to this year's Accounting Principal's Workonomix Survey, we're spending a pretty penny on coffee costs—$25.70/week for men and $15 for women. As for lunch, 22 percent of the workers surveyed said they prefer to dine out than brown bag it (35 percent), with men spending more ($46.30/week) than women ($26.50). Likewise, the younger you are, the hungrier you are: Those falling in the 18-24 age bracket spend the most ($45.30/week) on lunch.
