Dunkin' Donuts rated fastest drive-thru of national restaurant chains

A new study ranked Dunkin' Donuts as the fastest drive-thru of national restaurant chains.

QSR Magazine reports that customers wait an average of less than four minutes at Dunkins. That's well ahead of Chick-fil-A's last place finish with an average wait time of almost five and a half minutes.

McDonald's, Hardee's, and Arby's were among the other slowest.
