I’m going on a blind date and he invited me to a restaurant where the entrees are -25.

I really hate to spend that much money on food, but I didn’t want to be like "ummm that’s too expensive can we go somewhere else??" lol

I’m 19 and he is 21.

Since he asked me to an expensive restaurant would you assume he’s planning on paying?
Should I just offer to give the tip or something?
