I'm not saying all of them are, but some do it, they all thing since these people emigrate to "their" country, they all should just talk in English, instead of their own prefered language, even with their frends, which sounds completely unreasonable and arrogant.
but i think for those who only use english while they travel, they were either ignorant of the situation of a country, as to presume everyone can speak english...or too lazy to even care... lol
but yea, sometimes you(travelers) just need to be aware/prepare that once u reach an unknown teritory, make sure u have the right tools to help u around the place (i'm refering to.. GUIDES)..or better yet.. get a mates(friends) who live locally. free accomodation and tour yippie
