Do you think joking at someone else’s expense is funny?

I met a new acquaintance and their way of joking is making rude comments. Ordered a decaf coffee and the first joke was, “yeah you don’t need any more caffeine”. Second joke was a garbage truck drove by the cafe and I asked, “what’s that smell”, they then replied with, “YOU”! Looking back it was funny, but in the moment I was definitely not laughing. Keep in mind the is only the second time I’ve hung out with this person.
