Yeah, I worked grocery for a couple years and we were instructed to do that, but we were also constantly understaffed and discouraged from taking the time to do so, so it often was only done on products whose sell by dates were within a couple months of receiving (dressings and the like).

I vividly recall discovering one night that my coworkers hadn’t been doing this for our coffee section, and my acting manager was a tad passive-aggressive when he found that I’d spent about 30 minutes stuffing over 100 bags of coffee beans into boxes so it could be tossed (or given to a discount store or whatever). Some of the bags were 5 years out of date.

This has led to me checking the dates of every perishable I pick up at the store.
