Practise your English

How hard is it to improve your English when you live in a hostel with 95% of French people!!! But I wont stay a long time here. Basicly I will rent a room above the pub and live with Australia, South Africa and New Zeland people! At the moment I watch TV... Maybe too much! Whatever, I learnt a lot of "new words" for example: "fella", "dunno", "still" (water) and some expressions like "you crack". I bought a book called "The Bloody Chamber" but I haven't started readding it yet. I don't really improve my English at work cause I always repeat the same things:
Hi!
Do you want a glass?
With ice and lime?
Something else?
With your fish and chips would you like some peas? Mushy peas?
Do you want an extra of bacon? of burger? of cheese? of oignon rings?
How do you prefer your meat?
Do you want an extra pudding?
Where are you sit?
OK it's £XX
Your change
Thank you!
Next, Hi!
The ladies are downstair and the gentles are upstair. (loo)
