When I’m at the grocery store, buying perishable products, I’m always careful to check the expiry dates (aka Best Before dates.) I can’t afford to throw food out so I’m always very careful not to buy short-dated stuff.
Especially milk (aka half-and-half creamer). Gotta have some widener in my coffee, or it’s all hot and black and uncreamy. So when I buy my coffee milk, I am very careful to check the date on the carton. The 10% stuff is usually good for 6 to 8 weeks, and I usually go through it in 10 days, so it’s almost never a problem. Nonetheless, I always check the dates.
(I also have other rules, such as I never take the first one or the last one… the first one is half-exposed to the unrefrigerated air in the grocery store, and the last one is suspect by virtue of hiding at the back, so I always take one from the middle.)
Anyhow, so I recently stumbled onto a new conspiracy with these so-called best before dates. See, I brought home a carton of coffee milk, and put it in my fridge. No big deal. The following morning I took the carton out, and was surprised to find that the best before date said the milk was going to expire in a week. I know it said it was good for a month, when I bought it.
