Well the average for a city with a booming nightlife is a lot higher. I guess these would be considered outliers as the bartenders/strippers/waiters I know drive Land Rovers while I drive a Civic. I have a bachelors degree in finance, they have a masters degree in silicone.
Also, regarding the minimum wage, it is approximately 7-8 CAD which at a full time level equals about 10K less than the average salary so they're not starving to death.
