How does Cheryl Summerbee keep from getting bored at work?

Cheryl Summerbee is a check-in clerk at Heathrow, a job that is fairly repetitive and can lead to boredom. Cheryl, however, has turned assigning airplane seats into an art form, playing matchmaker with single people and punishing rude passengers with seats next to crying babies or the toilets. She takes great pride in surreptitiously arranging matches between lonely people and advancing the cause of romance.
