The movie is just imitating life. A sad fact of course.
One way to really get back at these Tagalog snobs... don't speak Tagalog to them when they're in Cebu. Speak in our dialect and only in our dialect, ug mahimo apili lang ininglis ginagmay. Kay ug kitay moadto sa Manila magtinagalog gyud ta. Pabinisayaa pud na sila diri. Aron magkat-on sab na sila. Mga anti-pinoy gyud ni sila!
This is what i always do when i encounter some of these "racist" northerners.
