What do I need to say when handing out leaflets for the first time?

Hehe, don't be so nervous. If you don't want to say anything, don't say anything. Just give the flyer directly.

If you want to be more careful, you can briefly introduce the contents of the leaflet, not as good as the leaflet of the newly opened hotel.

You can say, "Sir/Beauty, please find out about the new * * * restaurant nearby ..." Ellipsis can contain priority content. Just specify what is attractive, and when everyone hears what they are interested in, they will publish it faster.
