On tinder you get like unlimited supply of girls. Ask 20 of them out on the same day some of them will agree, and you can have a date with several girls at once.
dont spend a lot of time chatting. After a couple of messages say something like:
"You seem like a person who I might like. I am kinda busy and cannot chat a lot, but lets have a coffee next week. ITs only 20 mins, if we like each other we will do something else, if not 20 mins is enough to understand that and we dont need to waste our time chatting. What day is good for you, Tuesday or Thursday?"
Look, this is Tinder, you can say anything you like, you may even suggest to have only sex and nothing more in your first line. And you gonna get positive responses sometimes. With almost zero investments.
