I keep my first dates to a drink. I earn a great living so money is never an issue but I don't spend more than $65 on a first date. Alcohol costs more in Canada, where I am from , than it does in the USA or Europe.
When the bill comes I will pick it up and I'll say, " OK I will pick up the check and you can pay for the tip or you can pay for the check and I will cover the tip . Girls will usually want to cover the 20% tip. You get the girl to invest. Only an AFC would cover the whole thing. I have had girls cover the whole deal and then I offer to do the same the next time.... It's a smart way to get a d2
*Disclaimer- If you have f-closed a girl then it's ok to cover everything.
I never do anything else except drinks on d1.
