Cigarette smell from delivery, courier, and A/S technicians visiting homes

I really wonder how much they smoke while driving.
The smell lingers even when sharing an elevator with them.
When I receive packages, the smell is completely soaked into the items.
Whether it's A/S technicians, home appliance delivery personnel, or internet installation technicians,
the cigarette smell clings to them so much that it's a real struggle even after they leave.
I wish their companies would take some kind of action.
I don't feel comfortable telling them directly because it feels rude,
so is there any way to resolve this?
