Because yeah, that one there has clearly been chewed upon.
The employees probably view the scraps as trash, and perhaps they aren’t even allowed to snack on it. This signals that a hungry worker grabbed a quick bite, then tossed it back in the bag, unaware their manager was going to sell this off for $5.49 to a paying customer.
Some people brought up a good point that this place is seemingly misusing the app.
The point of the app is to sell off your food that doesn’t sell well otherwise. For instance, maybe if you run a donut shop, and notice that your bear claws and lemon tarts don’t sell well, so you put those in your “mystery bags.”
Using this app as your personal trash bag isn’t the move! If this place wanted to do that equivalent, they should be making a sandwich out of whatever ingredients are near their expiry time, or maybe using a bread that never sells out. Just tossing the customer a bag of literal scraps is rather ridiculous. The shop could be turning those scraps into croutons instead.
