What's Predictable?

There are a lot of things in life that can be pretty easily predicted.  There is a pattern and it can be followed.  Well, the restaurant industry does not make prediction very easy.  I looked at today being Monday and figured on us having a fairly slow day.  I staffed accordingly.  Monday's just haven't been that big, especially of late.  There was no reason to believe we would stay constant throughout the day.  Well, it happened.  It was great.  I ended up having to work later because I tried to anticipate the load based on the last several weeks and figured to have nailed it.  Not so.  We made it though.  Pushed through it just fine.  It is just hard sometimes to know exactly what is predictable.
