There's this guy I work with at a restaurant normally he's an expo but occasionally gets scheduled as a host. While he's working an expo shift and I'm hosting everything seems to run normally. He's kind of an egotistical, loud mouth, who can be really nice and considerate depending on the situation and what needs to be done. When we end up hosting together his mere presence infuriates me, not sure why. When I know he and I will be directly working together I do my best to get a proper sleep, eat well and start my day off right, and as always the day starts off fantastically until he shows up to host, and my mood instantly drops and my attitude comes out. I guess I'm just looking for advice on how to manage whatever it is that's going on with myself..
