I've never minded it, but I've seen in other threads where this has been discussed that there are quite a few guys who don't like it. They probably aren't interested in the lady to begin with and don't want to be put in a position of explaining why they're not interested.
I would only advise it in those cases where the guy has seen you before (and seemed to have enjoyed the encounter) or has otherwise expressed an interest. Frankly, I'm not likely to become a repeat customer unless I'm solicited...too many other fish in the sea tugging on the line for me to arrange dates with everyone I'd like to see.
