Show up on time. I learned this from the mentor who I call Bigfoot in Kitchen Confidential. If you didn’t show up 15 minutes exactly before your shift — if you were 13 minutes early — you lost the shift, you were sent home. The second time you were fired. It is the basis of everything. I make all my major decisions on other people based on that. Give the people you work with or deal with or have relationships with the respect to show up at the time you said you were going to. And by that I mean, every day, always and forever. Always be on time. It is a simple demonstration of discipline, good work habits, and most importantly respect for other people.
