I'm a southerner, but recently noticed I'm the only one who seems to say "tin" rather than "can". I think I got it from my Dad, who's from Birmingham. Meanwhile, my Mum (from Winchester) prefers "can".

Which do you/people in your area tend to prefer and is this a regional thing?

EDIT: It has come to my attention that I should probably have been more specific. I'm talking about the container that beans, soup, and other foodstuffs are sold in, not the many other uses for both of these words. Thanks for all the wonderful comments though, they gave me a good laugh!
