Wasting Time

What is more a waste of time,
Than wasting time...
Not wanting to hang around a garage,
Waiting for your car to be repaired.
So you walk leisurely,
Buying coffee,
Looking in windows,
Reading your iPhone...
As the charge runs down,
Until it gets to 5%
And you turn it off,
So the garage can call, when the job is done.
But, even unused, the 5% dissipates,
So they can't call you
And you can't call them.
And so you waste more time...
Enough time you hope,
The repair will be done...
And then walk back
Only to find, the part they ordered 
Has not yet arrived. 
    It'll be at least another hour.
    We tried to call,
    But you didn't pick up.
