<human>: Could you distill the essence of the text into 1-3 sentences?

So I work as a bartender at a corporate restaurant.  Because we are not an independent restaurant, the people who work there get away with things that would get you instantly fired at an independent restaurant.

One of my coworkers is fucking useless.  She makes nothing.  She stocks nothing.  She cleans nothing. She was caught giving free drinks to a secret shopper and not fired - merely suspended.  She is constantly calling off work and showing up late.  For whatever reason the managers let her get away with murder.

The calling off and being late thing drives me up the wall.  I work the Monday AM shift.  I make zero money on Mondays.  She is supposed to be there by 4:30p, take a 30 minute dinner break.  This never happens.  She is usually 15 to 20 minutes late and then goes on break for 40 minutes.  By the time I leave it's 6p or later.  The only consolation is that her laziness lets me pull in some money from the happy hour crowd.

Revenge part:  Monday night was a double whammy: Monday Night Football and the World Series here in St. Louis.  This awesome regular gave me tickets to the WS game.  My coworker waddled in 15 minutes late as per the usual.  The bar was packed.  We have one cocktail server.  It was at the point where everything was about to collapse.  The cocktail list was brand new as of Saturday.  I created all of them.  She knew none of them.

I said, "See you later".  She looked at me and stammered, "But... I want to eat dinner".

"Too bad.  I'm going to the World Series.  Find a manager to cover for you," and I ran for the door like an Olympic sprinter.
<bot>: Lazy coworker spends next two hours ruing the day she was born.  I drink beer and go to the World Series.
