Iīm almost sure I heard And you! as a reply to Have a nice day! once, in Regentīs Park, London... Could I be mistaken?
No, you were probably not mistaken. It is a very common and polite response, simply wishing the same on the original speaker.
Have a nice day!
"And you, too, have a nice day!"
It is so nice to meet you!
"And you, too!" (it is also nice for me that I have met you)
I was wondering if the guy said And you, too, and not simply And you... Because since that day, Iīve been saying And you! whenever somebody wishes me a nice day or weekend... I was afraid I was making a mistake...
Either way is understood.
