Today I had a taco salad for lunch in the cafeteria. The taco salad is freshly made in front of me. I saw the chef put a spoon of some kind of paste on the plate before putting on the taco shell. I wonder what he is doing, so I asked him. He explained to me it is just some bean paste used to glue the taco shell on the plate. He even demostrate the power of the bean paste by turning the plate upside down, the taco shell is not falling! It stops the taco shell from sliding off the plate on our way to have a seat. I am quite impress by this small invention. Innovation can happen anywhere. Even the chef in the cafeteria can come up with something new and useful. As an trained engineer, I should have come up with lots of creative ideas. Can’t lose to a chef.
