Treatment

Treatment 

Jacob (protaginst) walks into a cafe, and sits down expecting to be seved soon by the waitress. The waitress, however keeps going to seve the person sitted behind Jacob and he is unsure why. 

He tries to get the attention of her, but misses his chance everytime as he is  on his phone, tying his shoe up, etc. As his frustartion grows we see various shots of him reaching for something in his pocket, and the shot is replicated evertime he is annoyed. He eventually stands up and grabs the waitress to get her attention but is told "Just a minute". He gets annoyed and pulls out a gun, shooting the waitress. He then turns around and guns down the other customers in short space of time. He drops the gun and returns to his seat. 

After sitting for a while we hear the waitress ask him a questiuo, and it is revealed that the shooting was a daydream, and he about to be served.
