Industry secrets

I crave insider knowledge. This Reddit thread feeds my desire to hear what’s really going on in everyday businesses. It simply asks people “What’s an industry secret in the field you work in?” There’s a  couple hundred responses, like: Goodwill throws away most of what is given to them; in vodka, the bottle costs more to make than the vodka; it’s easy to get library fines waived; bouncers make up the rules; there is way more butter than you think in almost every dish at fancy restaurants; etc. — KK
