       | day, when they were marked down 50%. They were fun, and at that
       | markdown, worth it for the ingredients alone.
       | 
       | But they would often get left in the fridge for up to 4 more
       | days, and they were still 100% OK. So it really galled me to see
       | them shovel a whole bunch of just expired ones into a garbage
       | bag. Wait!! I'd happily pay the 50% price for those (especially
       | the super yummy Thai Basil Beef!) even one day later! No, sorry,
       | into the garbage they go. Never been a grocery store dumpster
       | diver, but that wouldn't go around here anyway, if those weren't
       | securely closed, the raccoons (and worse) would have a field day
       | and boy do they make a mess.

       | 
       | I have mixed feelings- obviously they're identifying stuff that
       | would just be waste, but it frequently ends up just sitting
       | around forever because who needs a case of olive oil when you're
       | 75? There is also an entire closet which is filled with
       | hydroflasks. Often the whole area smells like beer, because they

       | but they were making a few thousand dollars a year...)

       | various tools, a small aquarium...
       | 
       | I worked in a grocery store so didn't have the need or gumption

       | fun), except for one spot: the town Krispy Kreme. Sneaking around

       | a fresh looking box nestled on top of pillows of old donuts in
       | garbage bags.

       | Sneaking them into the cheap movie theater was the next

       | One day, my parents were having a party and we were playing video

       | for eating out of a dumpster...we laughed and hatched a plan:
       | sneak out my window so they thought we were still playing games,
       | zip to town, grab some donuts and offer them to the party. Except
       | one problem: when we got there the dumpster was bone dry. The
       | cleanest we had ever seen it. Puzzled for a minute I suck it up
       | and went to the drive through to buy a box of donuts at long
       | last. But then I took the sharpie in my glove box and largely
       | scrawled yesterday's date. We snuck back in the window, popped
       | back into the party, proceeded to display the "expired" box of
       | donuts, and I pulled one and took a big bite. My aunt was
       | exasperated! We passed the box around and it was fun to see which
