When we met with ours, we had already bought our own Starbucks since we were there early, so they actually went up and bought us a gift card for next time!
We pay for our clients when we meet at a coffee shops so they might step up. I would just go in planning to pay for your own drink and then if they offer to pay, let them. You might have to meet/interview several photographers before you find the perfect one and you don't want to be bankrupt on coffee meetings :-) Have fun and best of luck planning!
A Wedding Fanatic!
