Clueless (1995)
in this Amy Heckerling classic (which we LOVE and can quote for hours!), Cher (Alicia Silverstone) asks her maid Lucy (Aida Linares) if she can ask the gardener Jose to clear out the bush and Lucy replies, "He's your gardener, why you don't tell him?" Looking completely confused, Cher replies (matter-of-factly, we might add): "Lucy, you know I don't speak Mexican," to which Lucy replies, "I AM NOT A MEXICAN!" Cher's step-brother Josh (Paul Rudd) has to then explain to Cher that Lucy is from El Salvador and that it's "an entirely different country," to which Cher replies, "What does that matter?" Forget the fact that Cher thinks Mexican is a language, but she also assumes that all Latinos are Mexican and that Lucy, her maid, is Mexican. The popular movie quote has made its way into the pop culture consciousness and it's something we can't help but laugh at, but at the same time it speaks to the fact that there are people who don't know that not all Latinos are Mexican, and that don't understand that Latinos come from various countries.
