There are many such differences, and you don't have to go to a foreign country to hear variations in vocabulary.
I know four different words for a banana, and four different words for a child, because I lived in four contiguous countries. And I've since learned other words for these two objects just by participating in these forums.
The same thing happens with English. There are marked differences between the English spoken in America, Britain, Australia, Belize, and elsewhere. You may even find that your neighbor uses different vocabulary than you do.
The differences are vast and the list could go on and on. Some of these variations cause misunderstandings, much like what could happen if someone from England offered someone from the States their flat and neither was aware that the word is used differently in each country. The American would fret about how to respond to such a stupid offer, and the Brit would wonder why the Yank went on about cars and the lot.
