I must admit i do a lot of it at my work and get really annoyed, i try to be frugal and use the service users food up in the best possible way,but other colleagues dont bother to check the dates in the fridge, and as i deal with vunerable people cant take the chance by using out of date food even by one day,would do at home,anyway heard that its the big supermarkets that dont help this situation,they throw loads of out of date stuff out,there excuse is that its health and safety rules and even staff cannot purchase it at a reduced price!!!
