A character with a job might have fun with it, or they might hate it. But no matter what their thoughts on their occupation are, all bets are off once their Arch-Enemy or some other person they dislike walks through the door. Because now, their job requires them to serve that person they hate! If they were enjoying their job, then this will probably be the start of the Disaster Dominoes. If they hated their job, then expect their Rage Breaking Point to be coming up soon.
This trope is when a character working now has to suffer through providing service to a person they hate. While it's possible that they could focus on completing their job over their personal thoughts on the customer, Rule of Drama means that it's very likely that their hatred of their customer will get in the way. They might begrudgingly perform their duties, attempt (and probably fail for the sake of the plot) at refusing services, or sabotage the customer. If the customer hates the worker too, they might try to be as unhelpful as possible, assuming that their mere presence isn't enough to cause the worker intense anger. A put-upon protagonist might go and declare Take This Job and Shove It.
This may happen during Villains Out Shopping to the hero's work place. Contrast Go-Karting with Bowser, where enemies have fun spending time with each other. Unlike that trope, this one will always be a source of conflict. Also compare Enemy Mine, where two enemies work together to complete a common goal. See also Revenge Is a Dish Best Served, when the protagonist is tempted to mess with (or actually does mess with) the nemesis's food or drink order.
