What response to use for not buying girls drinks?

[Satan Psycho]

I use this one whenever a girl asks me for anything:

Her: Will you buy me a drink?
Me: No, but you can earn a drink.

Then look at her like you know she knows what you mean. This always instantly creates a frame of flirtatious playfulness.
