Best before / Use by...... What a scam!! Spend ages tossing perishables about in the supermarket seeking the holy grail of the longest dates; stack them all up in the fridge and as sure as night follows day by the time you find it again it's past it along with rice pasta and cooked veg that was being left aside for another day or to feed relatives...... <grrr>
If you;re single it's very easy to end up going to the supermarket, buying loads of stuiff with best intentions to eat it during the week rather than go out and then get to the following saturday and realise you have a load of stuff in the fridge that's out of date and some of it you didn't want in the first place
