Have you heard the expression, " Being on time is 10 minutes late."?
Do you slide into work at exactly the appointed time? Maybe a few minutes late. Meh, it's just 5, 10 minutes right?
Except I'm waiting. Waiting to make sure you are showing up. Waiting to start my side work. Waiting for you to punch in so I can tell you what is going on with the table that just sat down in your section. Waiting for you to read the features for the night, watching the tables continuing to stream in, as you get ready to get on the floor.
It's not about the 10 minutes. It's about respecting other's time. It's about being a professional. Yes, I know you don't get paid enough but does showing up late help that?
