Advice on my date's behaviour, should I go for a third date?

So I've been out with this guy a couple of times altho he's nice, his behaviour surprises me. For context, I'm mindful of a guy's time and money so unless I feel a mutual strong connection, I typically only suggest going out for coffee on the first date (I decline their offer to go to fancy restaurants and suggest coffee instead).

So I went on a first date with this guy, he was shy, and kinda inexperienced with dating but it went well. On the second date, he paid but I suggested that I'd either cover him on the next date or pay back my half. He said I could just pay him back my half so I paid the $12, but he got back to me saying it was actually $13.20. I was shocked, he's interested and wants to meet me again, but seriously? Being petty coz I accidentally underpaid him by a dollar?

I don't know if I should say yes to a 3rd date or just leave it here? He is a perfectionist and I honestly would've even been fine to pay for the date myself, but him being petty over a $1 is just ridiculous.
