You can't reason with emotions. Accept that people will act emotionally (illogically) and make a conscious effort to not let it disturb you. Stoicism at work... Make an effort to be nice to people. Treat people who serve you with gratitude, even though you are paying to be served. Look them in the eye, smile and say thank you. Spread some good feelings. Emotions are like weather, they come and go and sometimes cloud people's good judgement. Focus on bettering yourself in this regard, because ultimately your own mind is the only one you can control.
