Who the heck gets taken out, except children? We may go out for dinner as a mutual decision but as adults we are not taken. How very antiquated.
It’s just a saying.
Lots if people get asked out to dinner, to the cinema etc.
You agree to it obviously but the initial decision was the other person and so technically they’re taking the other person out.
It sounds like OP is asking for suggestions for someone they have been talking to.
