It's easy to ignore store codes you hear in Missouri stores. Most are meant for other employees or departments and don't involve you. However, there is one code you need to be aware of. If you hear it, you might need to run as if your life depended on it because it might.
I tend to mentally ignore any store announcements when I'm shopping in one of the zillion Illinois stores I frequent when running family errands. That's actually a very bad idea and this is a great example. If you suddenly hear "code blue!" over the intercom, you're probably in big trouble.
The internet is a great place to complain. This is more evidence of that. Shoppers around the country were invited to sound off about their least favorite places to buy groceries and boy did they produce a list. Missouri is loaded with 128 of the #1 least liked grocery store that shoppers claim they loathe, yet come back to time and time again.
