"Old fashioned" expressions that young people have never heard.

I was quite amused at the checkout in our local supermarket by the reaction of the young checkout cashier, when -not quite hearing what she said - I said "I beg pardon".
She truly didn't know what I meant.
Is this a local (Cumbrian) expression? It means 'what did you say' or 'pardon', or 'what', or 'eh?'.
Is it country-wide?
Do you use old fashioned speech? If so - what?
