Eating through the grocery store

This made some national news, don't know how many of you saw it:

Sandwich Arrest Stirs Debate Over Eating in Stores

So basically, this woman and her husband got arrested because they didn't pay for some food they ate in a Safeway store in Honolulu. They chowed, "forgot" to pay, and were stopped by a security officer. Both charged with some petty misdemeanor, but their 2 year old got spirited away by child protective services for the night. Their lawyer said "contact the media" and now its this big kerfuffle about whether the store was too harsh for arresting her. I feel a little for her, but then I think about all the times security must hear "I forgot" by brazen thieves and I understand their point of view.

I guess I'm asking what y'all think about eating food in a grocery store. Not talking about samples--talking about grabbing a few grapes to "sample" or just doing what this woman did and eating a sandwich right there in the aisles before (not) paying for it. Do you do it? I wouldn't feel right...and I'm having a hard time figuring out why, if your hungry, its such an imposition to just take 30 seconds and pay for it at the register. But I know people do this all the time, so maybe I'm wrong.
