The "Onion in the Varnish"

 The Vienna Sausage Company moved its operations from an old, improvised building to a modern, state-of-the-art facility — but the sausages didn't taste as good. For over a year, the company strived to fix this issue without success. One day, they remembered one of the ex-employees, Irving - he used to take half an hour trips through various production rooms to move the sausages from the filling room to the smokehouse. It turned out that these daily commutes were infusing some secret flavors in products - so they decided to replicate it by adding a new production room modeled after Irving's journeys. This enabled them to recreate their original sausage flavor.
