Wanda Dollard is the sarcastic cashier at Corner Gas. A single mother to Tanner, she loves licorice and root beer, makes fun of Hank which sometimes results in Wanda chasing Hank. She has mischievous and caustic personality and often enjoys lording her knowledge over others. She eventually attained a Ph.D. in theoretical physics and she still works at Corner Gas, albeit with a pay raise. She's portrayed by Nancy Robertson.
Lacey arrives in Dog River after inheriting her Aunt Ruby's café. She meets the town's quirky people including her business neighbour, Brent, owner of Corner Gas, and Wanda, who makes fun of Hank's suspicions about Lacey. Lacey offers a Pilates class which offends Wanda, who teaches a "mat class." In order to impress Lacey, Brent agrees to babysit Wanda's out of control son, Tanner, while Wanda goes to the dentist.
Wanda is one of the few residents of Dog River who has gone to college. ("Friend of a Friend") She holds a degree in linguistics with a minor in comparative religion but took classes in many other subjects as well.
Wanda has moved at least three times in Dog River, as her house keeps changing. Her first house was very isolated and surrounded by a large property. ("Oh Baby!") Her second house, where Hank destroyed her bird bath and smashed her car window, was in town on a small property. ("Telescope Trouble") Hank stays in Wanda's last house, which is also in town. ("Good Tubbin'")
Wanda's height (5' 0", which should have been in centimeters) and birth date (April 16, 1968) was seen on her driver's license. The date originally read 1966, but was altered to read 1968 so that Wanda was the same age as Brent and Hank. ("The Accidental Cleanist") Her birthday is the same as Wes Humboldt. ("Block Party")
By 2014, Wanda's son Tanner is in his teens and is looking for colleges to attend. He is not admitted to any of them, ends up working in Northern Canada, making enough money to send Wanda on a cruise. ("Corner Gas: The Movie (Film)")
