I might get embarressed, irritated, or flattered depending on who it was.
I would love that!
it all depends on the person, the situation, the location. if i was on a date with someone and thats how they greeted me, i would think its romantic.
I would probably like it and think the man had nice manners.
It would depend a lot on the situation, the fellow, the way it was done... but it could be very charming.
