Slipping through
There are some items of crockery and cutlery that are interchangeable. You can use a side plate instead of a dinner plate, or a teacup instead of a mug. You can’t always swap in something else, though. Not if you want to eat the meal that you have been looking forward to.
Here we have another example of how quality control is an essential part of the manufacturing and production process. Mistakes happen, especially in a factory with multiple products, but you would think that someone would notice that this box wasn’t filled with spoons. No one is going to be enjoying the 30% extra tomato soup with these.
