I have a date with a girl I met on tinder in a few days. We're grabbing ice cream and walking around since she's not 21 yet. Now, when we grab ice cream, should I pay for hers too? I've seen conflicting views on this. On one hand, it can be seen as beta, but on the other hand, I'm older than her, have a higher paying job, and am the one who suggested ice cream. What do you guys think?

Also worth noting: when I grab drinks with girls, I either get there before them and have a drink already, or I get the first round while they get the second. Neither really applies here.
