Last summer I subbed for one month and I tried to ask about customs in finnish and she always replied to me with broken english. When I said that using a cheap agency and indian chatters is not good publicity for you, the replies stopped for a while.
Then the next day she answered me in finnish and said that "she's really sorry because at first she didnt feel comfortable talking dirty in finnish but she'll try from now on". Absolute joke and a shame, because I agree that she's really funny and hot.
