People like you are why we are living in an increasingly lower trust society, with for example having items behind locked door in shops.
Reminds me a bit of the shopping cart theory.
Think about blaming the grocery store replacing workers with no one in particular before you blame some college pranksters.
Grocery stores in general consolidating, laying off workers, leaving them without pay/benefits, taking advantage of greedflation, etc., is a bigger drain on society.
trust goes both ways. you can be cynical about people who take things without paying, i guess. i prefer to be cynical about the corporations who run and stock these grocery stores with substandard products at artificially inflated prices that benefit shareholders and disadvantage people who need to eat food to live.
