It's wrong to criticize a person just for their appearance.
Dwayne is at work in a retail shop and is helping an overweight customer in the fitting room who has selected too small a dress.
Dwayne wants the customer to try on a larger size, as she might rip the one she selected.
Dwayne mentions to the customer that the dress she selected runs very small and says most people need a size up.
Dwayne asks the customer if she thinks somebody of her level of activity could truly fit into the dress she selected.
The customer agrees to try on a larger size and doesn't feel insulted.
The customer is embarrassed and infuriated, insisting on speaking to the manager about Dwayne's rudeness.
