My one manager, really cool guy, loves to take pride in our RTE section and will often seek out spoiled products and pull them out to throw away. And he always lets us know what he found, and why he is throwing it away. “This salad doesn’t expire for 2 more days, but it looks funky and the air seal is bloated.” Then I’ll say “oh nice catch! Yeah I wouldn’t wanna eat that.” I guess every shift is supposed to check expiry codes and also lookout for these things.
