“My boyfriend is weird about tipping”

I’d like advice on how to handle some things I’ve noticed about my boyfriend of almost three months. A few times since dating, he has sent back food at a restaurant — not because the order was wrong, but because the dishes did not live up to his expectations. I think I have sent dishes back maybe like two times my entire life, and it’s been because the orders were wrong.

Then on one occasion, we ordered two glasses of wine, and the waitress indicated she would bring us a carafe. When he received his ticket at the end of the meal, the carafe was either $2 or $4 more than it would have been if we would have just received the two glasses of wine. He proceeded to write a note on the ticket. I was so embarrassed. To make matters worse, the next morning, we went out to breakfast and I paid. At the bottom of the receipt it had gratuity recommendations and $7 was 15%, so I tipped $7. He then asked me why I only tipped $7. The night after he didn’t tip a waitress and wrote a note on a receipt!

I can’t decide if I should say something to him about this. I Feel like this could be a character flaw, in that he is extremely picky.
