NO GRACIAS! explain to me

Two different things, Avi.

First, at any restaurant I have ever eaten in in the USA, I have never had someone come up to my table and interupt my meal trying to sell me gum, trinkets, time share, turtles, braid my hair, or any other thing. So for it to happen here is not what people are accustomed to. (I have been here a long time and understand what it is about but newer people might not). When you are trying to eat a meal and you have 20 or so people interupt your meal, you get tired of it and sometimes you are no longer happy to see others. I think a polite no, thank you is proper. You must realize when you come up to someone you might be #21 in the last 30 minutes so you get the no, thank you without them hearing you out. That is just life.

Second, is how many necklaces, plates, hats, can one person buy? I have bought all this stuff in the past but no longer need any of it.

I know lots of the vendors and talk to them about their daily lives, but then there are days I don't want to be bothered with any thing except to read my book.

You, on the other hand, can bother me whenever you want to and I will be happy to practice my Spanish with you.
