While I don't necessarily condone shoplifting, hypothetically, I'm willing to turn a blind eye if the person is stealing essentials (food, deodorant, soap, etc). Depending on what they took and how much, I'd just let 'em have it, but give them a stern warning not to come back, no need for the police or anything. Maybe I have too much of a heart and conscience to work a job like that.
I feel like loss prevention and/or employees who go “above and beyond” to stop a shoplifter, especially if what they're taking is very minimal, are taking their jobs a little too seriously, at the end of the day you're not getting any promotions, pay raises, or public recognition for stopping a shoplifter and the store, especially if it's a big brand outlet, they're not losing any major profit from minor theft as they might have you believe.
An aunt of mine once told me how, when she was coming up during the late 70s/early 80s, she worked in a grocery store, and stopped a shoplifter just before they could leave the store, and revealed they had a couple of packs of ground beef underneath their coat. Only two employees were working that morning, herself and another who was in the back stocking shelves.
Well, long story short, quietly she told the shoplifter they could keep the meat, but just don't come back. She ended up paying for the items herself to avoid any trouble from management and told me she did that every time someone shoplifted food because she didn't think those hungry and in need should be criminalized and institutionalized just wanting something to eat.
