Alternate Character allowing Player to use object [Solved]

[Dervish]

I am sure this is just a matter of assigning a particular interaction but my little mind can't seem to figure it out.  Basically the situation is a bum is basically protective of his trash can and only until the player gives him something will he allow the player to mess with the garbage can... So what either interaction could I use or what script could i use to stop the player from doing this until they have give an item to the bum?  Sorry if this is simple but it is the beginners technical forum
