In this experiment, we tested a standard modal (with 2 choices) against a "Maybe Later" one (with 3 choices). One of the choices in the variant allowed users to postpone their decision with a "maybe" which would enable a floating bar at the bottom of the screen.

Both modals also appeared instantly after a page load.
