I can click my friend's name-link and it will take me to their page. From there I can click User Info and that shows me if they're on a paid account, how many icons and what-not. From there I can establish if they have a paid account and if I do decide to gift them with more time there's the "Shop > Gift Paid Account" option in the blue bar under my own name.
For example, if I click your user info I learn this right off the bat:
