Chefs Share The 18 Things You Should Absolutely Never Do In A Professional Kitchen — But Not For The Reasons You'd Think

Professional cooks might not be a particularly traditional or reverent bunch, but they’re undeniably some of the most superstitious people I’ve ever encountered — and I was raised Catholic. Restaurant kitchens have their own special set of rules and codes; breaking them is a risk you don’t want to take. In a cook's world, ignoring the 'rules' doesn’t just tempt fate, it practically guarantees you’ll be the one blamed when things go south (think: an unexpected late-night rush or a temperamental dishwasher).

Recently, in the r/KitchenConfidential community on Reddit, chefs and cooks shared the kitchen-related superstitions they do NOT mess with. If you work in the industry, some of these might hit close to home. If not, consider yourself warned: you’re about to open a pandora's box of culinary taboos.

1."If you shut down the kitchen 15 minutes before it is closing time, a customer will always walk in. "

3."If we have a slow night, and just do our thing, it stays a slow night. BUT! If I start making a batch of pizza dough to get ahead for the next day, it always gets busy right after I add the yeast to the flour mixture."

4."I was told it’s bad luck to sweep someone’s feet. It’s obviously rude and not necessary to sweep that close to someone’s feet, but I’m overly conscious about not doing it."

5."I call it the lucky ticket..."

6."If you gift a knife, include a penny with the gift for them to give back to you."

"The superstition is that if you take the penny in exchange, you 'sold' them the knife instead of gifting it. If you gift a friend a knife, it is believed to sever the friendship."

7."I was raised by Italians who always said, 'We don't believe in superstitions, but just in case...' So you bet I throw salt over my shoulder."

8."Having a quiet close is like pitching a no-hitter. No one says anything about it, or people will come in and ruin it."

"Just a few days ago, one of the cooks was dropping off some stuff at the dish pit about half an hour before the kitchen usually closes and mentioned, 'It was so quiet today, we'll start bringing up the kitchen soon.'

She comes back not 5 minutes later: '8 people just walked in.'

NEVER, EVER SAY THE Q-WORD BEFORE YOU ACTUALLY SHUT DOWN!"

9."If somehow you make an extra dish or one gets sent back, if you don't throw it out, you won't get an order for that dish the rest of the night."

13."I work in an open kitchen. Never look at customers walking past you directly; they always come in. I've even had them keep walking and then double back and come in."
