How do y’all respond when niggas keep telling you “I got that bud”. How do y’all politely decline?

I got about 2-3 niggas in my hood that do this and one of them chill by the store often and always saying “yo bro holla at me I got that za”. How do yall politely decline this? I know these dudes to say what up to and shit but that’s it.

One time a while ago I did reach out to one of these dudes when I didn’t have any bud but he didn’t have bud at the time. Now everytime he see me he telling me he got some new shit.

How do y’all deal with this when it niggas in your hood?
