NO GRACIAS! explain to me

Avi - I think Fran has given you the best advice in this thread. I believe your use of the phrase "good morning friends" sets off the immediate and almost involuntary reaction – “oh no another time share salesman ” which results in the automatic response no gracias. As tourists we are bombarded by them and after awhile it gets very annoying – despite the fact that we know that they are just trying to earn a living.

I think Fran’s idea of saying something like she suggested ("I live here. I like to practice my English and I wonder if you have any questions about Barra that I can try to answer") is a much better approach for you. I also agree that you will have more success if you don’t try to sell them tours as part of your conversation. On the other hand if they ask you what you do for a living then I think it would be OK to simply hand them your business card and tell them that if they ever want a very good tour of La Barra then this is how to get hold of you. Then leave it at that. If they don’t ask what you do, then don’t do it. The next time they see you they will be happy to sit and talk awhile knowing that you aren’t out just to sell them something. Good luck amigo.
