Does your bank offer an overdraft facility?
Does your bank here means the bank you're using or the bank you're working at?
It can be both. If you are enquiring about some information from any employee of the bank, then your bank means the bank employing him but usually it should imply the bank you are normally using to transact busines or personal account. So one says my/your bank while talking about matters related to the bank, as:
The auditors have already analyised your bank statement
Do you get your bank statement monthly or quarterly.
Have you availed over draft facility from your bank.
I shall pay you the amount after withdrawing the money from my bank.
