Dagupan City, Pangasinan

Filipinos abroad are often asked about their home province. I have been asked by this question several time during my 5 years stay here in Dubai. Dagupan City in Pangasinan is where I grew up, so everytime somebody asked me, I would tell them that I am from Dagupan, Pangasinan. But why is it that people always tell me " ah, pangalatok"? People outside Pangasinan knows pangalatok as the dialect spoken in Pangasinan which I know is wrong. A person who lives in Pangasinan is called Pangasinense and the dialect we speak in Pangasinan is Pangasinan but there are other towns in Western and Eastern Pangasinan that speaks Ilocano dialect.
