Of course sir, with pleasure

Scene 1:
One fine evening, I was traveling from Chennai to Mumbai by Jet Airways 8pm flight. The food served was good. For some reason, I didn't had my lunch and felt that the food was not sufficient. I stopped a passing by steward.
I: Excuse me! The food was delicious.
Steward: Thank you Sir.
Me: May I have one more Biryani.
Steward: Of course sir, with pleasure.
Scene 2:
I went to a restaurant with one of my friend. I browsed the menu but didn't feel like eating any of the items. I told my friend that I want to eat Biryani.
He replied-it's not in the menu.
I: Shouldn't we ask the waiter?
He: It's not in the menu, which means they don't serve.
I ignored his response and called the waiter.
I: Can I have one veg. Biryani.
He: Of course sir, with pleasure.

My friend was in a mood to argue with the waiter that they've committed a crime by serving an item unlisted in Menu; I had to persuade him not to do so.

Scene 3:
I was traveling out of country for a long term project. I had some issues with my State Bank netbanking and I needed a fresh login/password. I requested one of my friends to visit the branch with my passbook and enquire about the procedure.
My friend: Do you think that they will tell me anything?
I: Why not, you are represting me, their esteemed NRI customer. And you are carrying my passbook too.
My friend: Talk logical, customer information is confidential.
I: Of course it is. But you are not going to ask my balance, just a procedure for how to get a netbanking kit.
My dear friend reluctantly visited the branch. Waited for 5 min (yes sir, only 5 min. in State Bank of India, SPB, Branch Bangalore).
My friend: One of my friends wants netbanking access to his SBI account. Will you please tell me the procedure?
The Relationship Manager: Of course sir, with pleasure.

The bottom-line is - there are many things in this world which happen, you just have to ask for it. Don't hesistate.
