Costco and Sam's Club usually have their filling stations set up for one-way traffic, but offhand those are the only ones I've seen that way in US, Canada, Caribbean, and western/central Europe (though the Euro design of filling stations just off the highway encourages one-way traffic, it doesn't mandate it). Haven't driven myself elsewhere.
