A man eats his lunch at a Burger King in London.

The next time you stop in for a morning latte or head out for a restaurant lunch, take a look around – and don’t be surprised if you see a lot of young men standing in line.

A new survey of workers finds that men spend significantly more on coffee and lunch than women.

The survey, from staffing firm Accounting Principals, also found that younger workers spend more than older workers on lunch and coffee during the workday.

Overall, those lunches out and coffee breaks are costing workers a bundle.  American workers who buy coffee and lunch spend an average of $1,000 a year on coffee and $2,000 a year on lunch, based on the survey of 1,000 workers.

About two-thirds of workers buy lunch and half buy coffee during the week.

Men were slightly more likely than women to go out to eat, but they spent a lot more. The men who buy their lunches spend an average of $46.30 on lunch each week, compared with $26.50 for women who go out to eat.

Men who buy coffee spend an average of $25.70 vs. $15 for women.

The caffeine fix is a bigger hit on the wallets of 18- to 34-year-old workers. Younger workers who buy coffee spend an average of $24.74 a week on coffee, compared with $14.15 for workers 45 and older who buy coffee during the work week. Younger workers also spend far more on lunch than older workers: about $45 a week vs. $32.

Not surprisingly, a third of those surveyed said one of their goals for 2012 was to bring their own lunch more often.

Accounting Principals, a unit of Adecco, commissioned the survey in December.

Tip of the hat to Consumerist, which first reported on the study.
