It kinda depends on the culture, too. Like I date pretty casually up to the 3rd date, so I'm not thinking about like..commitment on the first and second. Even if someone is like "I really like you, like a lot" I'm not going to think "I have to commit to this person in return or tell them I have no feelings for them." (which is something that I've experienced with someone confessing his feelings before I knew him that well, and it was fine, we went on a few dates, I didn't really like him as much as he liked me, I let him down easy.)
Like I would just say "aw, thank you. You're a good friend. We'll should go out again to see how it goes." instead of a whole anxiety inducing explanation that sounds almost like the start of a breakup. It's so terrifying to talk about love and to be burnt when you love someone, that they don't need me to say I feel nothing. That's too harsh. Usually people wait until like the 2nd or 3rd date to be like "Sorry I don't have feelings for you," and they don't dive deeper than that unless they're asked. Also "I don’t have any particular feelings for you at the moment." sounds a little like they're not even freinds? But I don't know the context.
So the response written here sounds like person B is...explaining to person A what a date is. Which is kind of odd, like we know what a date is. It doesn't need to be said, not only because it's redundant but because because dating is pretty rough on the heart so there's no need to be 100% honest about your feelings 100% of the time. Like don't lie to your date--but don't say you don't like them before you need to tell them that.
Like I had a roomate who once dated a guy for 2 weeks, and at 2 weeks told him "we need to go on a walk" so they went on a walk to Taco Bell in the middle of the night and she was like "in 2 years, we will be married, or you will be married to someone else, and so will I, where do you think we'll be?" and like obviously he broke up with her on the spot because that's freakin terrifying to have that much honesty that early in a relationship. It's an overwhelming feeling. And like...this person B giving the full rundown of their entire relationship before the first date sounds like a person that'd break your heart on the way to Taco Bell at 11 PM, being real, so I uh would not date them.
So it's not that no one would talk like your example--I'm sure a bunch of people do, I've met all sorts--but it'd be a bit of a red flag.
