If you said "the guy," you're in the majority. In a NerdWallet study of people in relationships who had been living together for at least six months, 77% of respondents said that men should pay on the first date.

Apparently, this doesn't change as time goes on. When asked who pays on "date night," 56% of men said they pay, along with 0% of women (yes, zero). There are a good number of couples splitting the bill, though: 40% of men and 41% of women say they split the check on date night.
