Yea... "tacky" might be the wrong word here. "Cheezy" works better.
Neighborhood 'drivebuys' launching pellet filled plastic baggies from a vehicle advertising a lawn company = Unprofessional. Nor do I see any reason to make a potential customer, come out of their OWN house, walk down the driveway to clean up the 'litter' left on their property. Because "Litter" is exactly how they'll see it. But that's just my opinion.... trying to be as nice as I can without seeming like a 'jack@ss' too.
