Why does a grocery store need security guards wearing body armor? Edit: Judging by the answers, apparently this normal in the Bay Area/California? Wild...

They want to go home

For their safety. Unfortunatly it needed

I think I would rather have the body armor on and not need it then need it and not have it just makes sense if you're caring again and protecting a building in my opinion

Because they have been robbed at gun point even tho I don't feel safe because you never know if they are going to go crazy themselves but yeah its for the protection of the store . Thats what the manager has told me I live right down the street and shop there daily so I was concerned at first until I asked , Hope this helps .

I dont know always be prepared rather be caught with it than without it!! Its self protection probably a personal choice!
