Smash, Bags off, Door closed

It all starts with a scan,

My slaves have a cup of coffee in hand.

My door swings open,

My lights go on. 

People get on,

Bags go up.

My door swings closed, 

Then my day starts.

The people who pay me,

Get pushed to my seats.

My signs go off.

The clicking cart comes and goes. 

Bathroom Break.

Signs on.

Down we go.

Smash.

Bags off. 

Their day gets a break,

But I keep going.

Till one,

Smash.

Bags off.

Door swings closed,

And I get a break.
