- Men are the bigger spenders when it comes to grabbing lunch.

And coffee.

Men who buy lunch average about $46 a week...$20 more than what most women spend. And men who buy coffee spend about $10 more per week.

It all adds up.. to thousands of dollars a year.

That's based on a survey of a thousand workers from staffing firm "Accounting Principals"... which also found that younger workers spend more on lunch and coffee than older workers.
