I agree he isn't doing anything wrong and all though it makes you mad,asking him to move it will only cause tension. And have you talked with hume you lease from about it, maybe they know their neighbor has the stand there and don't mind,I would talk to your landlord first and if he doesn't know its there maybe he will take care of it,but I would avoid causing conflict, or your landlord may end your lease.I know as a landowner theres nothing worse than bad blood between neighbors.So let him decide how to handle the stand if he wants to at all.
