Actually, it's the reverse scenario. Especially on the first day, she insists to split the bill and if the guy falls into this testing trap then his dating with her could end here. If the guy resists, she still continues to test a bit far by offering to pay just the tip. Don't fall in this trap guys.
Quote from Vinny1:
You have to test women. If they agree to pay half the dinner bill on the first date, then you know you have a keeper.
