All he is receiving is that he put in all that effort and you nagged him about a tip he felt he could not afford to pay.

However, it would irk me too. I find it mortifying to be out with a cheap tipper and often throw an additional five or something when they aren't looking. I also don't go back for a second date if they are that cheap.

I think you need to let it lie for a day or so before bringing it up that you feel he is a lousy tipper and you would prefer less outings and more reasonable tips to go with them.
