Can't Win Regardless

The manager at my part time job was out of town last week.  During his absence, I felt we did pretty good.   Our food cost was good.  We exceeded projected sales.  We even managed to save man hours.  But this was not good enough.  His boss had to find something to complain about and we all know how the trickle down effect goes.  It's times like that when I feel I can't win regardless.  Despite all the good things that happened, the company chose to focus on the one bad thing.  Whatever happened to celebrating success?
