dating app takes so much time, the girls expect you to have a perfect funny reply or they lose interest. If the success rate is 1 in 10 and and you need to spend an hour on each girl, thats 10 hours to get a unknown punt. Paying for a punt is a way more efficient use of your time, you pick the right girl or you walk.
I guess, you gotta work out what do have more of? Time or Money?
