There's a certain etiquette to enjoying free samples at grocery stores. Take one. Pretend to listen to person giving the cooking demonstration/ handing out the samples. Walk away.
You don't shove as many samples as possible into your face then haul off and hit an old man who corrects you. But. That's exactly what Derrick Gharabighi, 24, allegedly did at a Costco in Burbank, Calif. on Sunday.
