Nope, sorry. Didn't mean it that way.
What I meant is that sometimes the head chef is working, sometimes the sous chef. Sometimes the kitchen is slammed and your food gets rushed. Sometimes your server is slammed and your food sits for a few minutes longer than it should. And sometimes, you order chicken parm, but then see your partner's tenderloin, and think, "Man, I should have ordered the tenderloin" ... and now all of a sudden, your chicken parm is just meh.
There are a myriad of reasons, day to day, hour to hour, why some folks will sing a restaurant's praises and others will barely give it a passing grade.
