Bad example. Lots of English-speakers all over the world say "serviette" rather than napkin. Perhaps the difference is that Canadians are not trying to be posh when they use the word? - clasqm
In that case, go ahead and remove the sentence about serviette!
Not unless I (or a Canadian, more likely) can think of a better example to put in its place. That's how it works here IMHO. - clasqm
In my idiolect, a napkin is made of cloth, while a serviette is made of paper. I'm guessing my idiolect is representative of wider Australian English, but I've learned to be not entirely sure. -- SJK
