I was wondering the difference between 'How will you pay?', 'How will you be paying',
Somebody told me as follows,
How will you pay? - talks more about the ability to pay, can you pay for this
How will you be paying? - what you will be using to pay like cash, credit card, etc.
Now, I am wondering, what's the difference between
How long will you stay?
How long will you be staying?
