Dunkin Donuts and Krispy Kreme are both giving away free donuts, one per customer.(Dunkin Donuts says you must purchase a drink. Krispy Kreme doesn’t care, no purchase necessary.) We’ll be stopping at both places on Friday. I mean, who can resist free stuff. So prepare yourselves and throw on your tennis shoes. If you plan on stopping at any of these places before work, we’d suggest you give yourself adequate time. But an hour or two in line for a free donut, no biggie!
