Look, we're not ones to turn our noses up at free stuff, but this coupon is just ridiculous.
The CFA Institute's David Schawel noticed this Google Offer for "free napkins when you buy coffee."
Below is the offer, from Otha's in Brooklyn, New York.
But that's not all: the coupon is only valid until April 29th. And there's 10 napkin limit. Better hope you don't spill coffee on April 30th.
