Ted, a supermarket employee, approached 50 random customers and asked whether they would be willing to discuss what they liked most about the store. He interviewed the 20 who said yes.

Is this a random sample of the supermarket's customers?

no it is not, a random sample would be the original 50 customers that he asked, since he only interviewed the ones that said yes, the population isn't completely random.
