South of Wawa (1991) on Netflix

Lizette, Carol and Cheryl-Ann work as waitresses in Joe's donut shop located in the small town of Stayner, Ontario. While naive and perpetually smiling Cheryl-Ann, whose outwardly happy existence is despite her mother being seriously ill, considers Lizette her best friend, irresponsible Lizette - who is the bane of Joe's existence - finds Cheryl-Ann annoying. That is why it is with reluctance that Lizette asks Cheryl-Ann to be the replacement fourth for an ill Carol in tonight's double date, thirty-fifth birthday celebration for Lizette to the Dan Hill concert in Toronto. Terry (Lizette's exterminator husband) and Terry's exterminator partner Simon are the other two in the foursome. Lizette needed to find that fourth as Simon, who just broke up with his fiancée Pam, would not go without a date, and Terry wouldn't go without Simon, as both men really would prefer to stay in town and go to the local hockey game. The events of the evening, which don't go according to plan, begin the process of each examining their relationships with the other three as well as with other townsfolk including Lizette's younger sister Darlene who has self-image issues, and Johnny "The Polak", the enforcer for the local hockey team.
