Doritos has quite a few commercials running on Super Bowl Sunday this year. This is one of the better ones they've ever done.
In this one, a young man is tired of waiting in line at the grocery store. He notices an elderly gentleman, who appears to be blind, in front of him. The guy tries to take the Doritos bag from him, but the cashier won't let him. After unsuccessfully trying to persuade the girl a couple of times, the old man finally has enough and whacks the guy in the groin with his walking stick. Ouch.
