The Customer then goes to the supermarket to pick up food for dinner. However people are even ruder to him there then they are at work. The real icing on the cake comes when he is next in line, but the cashier shuts the line down.
The Customer, thinking that it can't get any worse heads home to lick his wounds and prepare for the big business trip. However, predictably things start to go down hill pretty rapidly for The Customer.
The Customer is treated extremely harshly by the airlines, who don't recognize his reservation. The hotel doesn't realize he ordered a room, and then the next day he finds out that room service won't order him breakfast, despite the fact that he called for it early.
When he gets back to his home state, The Customer finds his luggage destroyed. He snaps and starts crying angrily losing it at the injustice of what is happening to him.
The Customer however has his revenge as he tells the audience that they have the power over those who insult them and to choose places that treat them well.
