How much should he pay for a first date? 😳😮😱

How much should a man pay for a first date? $20? $50? $100, 200, $1k? Rent? lol
Should he even pay? Should she pay for the 2nd or 3rd then? Or split the bill 50/50.
Or how about free or cheap dates like going to the park and walking around and talking getting to know each other.
