Hello, welcome to Lincoln Bank. What can we do for you today?
I want to effect payment under an L / C today.
No problem. OK... just checking for you. Ah, I'm afraid there aren't enough funds in your account to cover this transaction. What you can do is buy some US dollars, using local currency and we can credit your account with that amount.
That seems alright. What's the exchange rate like today? Good or bad?
