Actually i think it was a joke on TV, and no store that i know of in the States or in Europe employs "shirtless hunks" to bag groceries.
But hey, you live in the land of limitless opportunities...
Go offer your services to the nearest chain. maybe you'll start a trend.
Personally I think it's as close as you can get to prostitution, but that's your choice (I wouldn't buy in a store that employed shirtless people to bag groceries. I think it's demeaning, and probably not very hygienic either)
