Should men stop using this approach to try to date women?

A lot of guys (my uncle did this too) will ask to buy a girl dinner, the girl accepts, then the guy never hears from them again. I've heard multiple men talk about this. I can not imagine myself ever agreeing to go on a date with a guy if I didn't even think I would like him. And do women actually go to dinner with a guy just to get free dinner? That blows my mind
