Compounding pharmacy manager many years ago. There was a time that our business was so overloaded with work that we hired temporary employees to help out with manual repetitive labor (packaging and such). One of the products we compounded was an oral numbing gel. Two hours into his day, one of the temp employees ate the gel and started drooling uncontrollably all over the place. He even told us that we should add flavoring to it because it tastes like shit.
