The same people who do it for $15 working at Instacart by shopping for groceries at Loblaws and delivering it. Or anyone who used to work (or still works) for the minimum wage (you know, it is not high skill job). There are several big "we shop for your groceries and deliver to your door" companies with very little delivery fees, but, unfortunately, they do not work with Costco. The question was about the gig employment, and 2-hour job for the minimum wage is exactly what it is. In fact, I would be OK to drive to Costco myself so that this person simply load the grocery to the trunk (as Walmart and Loblaws employee do), so, it is actually $30 for 1 hour work. Pretty high pay I think. Or do you believe such job require higher pay? If yes, what should be the hourly pay for in-store shopper?
By the way, with such logic it is no wonder you are OK with old people having sex with underage girls in foreign countries (you can find the reference to it in the exact same place where you can find the reference where I say I am OK with any sexual exploitation)
