For the shoplifting thing, it depends which store it is. Big chain grocery store? Yeah, I couldn't care less what someone takes. Small single owner shop? Fuck you for stealing from that guy. Those stores struggle enough just trying to compete with the Walmarts of the world.
When the food is multiple grocery bags full of steaks I'm a little less inclined to a charitable view.
That said, I'm still not going to do anything about it. Intervening on the behalf of a grocery store is insane, even if I were opposed to what's happening. Not my monkeys, not my circus.
Wal mart is still the one and only store I used to steal from back in 90’s. Had to wear umbro shorts since they had that webbing in them and then grab a few CDs and beads to make necklaces that I would sell. By the time I got to high school I was over the shop lifting thing.
Most stores don't stop you. The security guards are just there for the police report and a description. That said, if you get recognized coming back to the same store, they will call the cops.
