Here's some working in a kitchen 101 for you. On a slow night, never say the phrase, "man, if it continues like this, we might be able to get out of here at a reasonable time" or any variation therein.
Not even ten minutes after my co-worker said this. Five tables all came in, sat down and wanted dinner. 😂 Needless to say, we're not going to be getting out of here early.
