Online delivery the other day, packed into fridge. Looked at the date on the top pack of pork and assumed both would be the same so decided that would be for dinner tonight. The bottom pack went out of date on Monday. My own fault for assuming but a bit peeved.
Some things I'm very strict on use by dates. Other things less so. Milk for example. You know when milk is off without a date on the bottle. Most things I would allow an extra day as I don't believe food spoils at the minute the clock strikes midnight and the date changes.
How strict/lax are others about use by dates?
