We do 1 large church and we have seen some funny things happen there, though we've never been low-balled or lost the account to a member there.
It's a very large, beautiful property, and I take a lot of pride in it, even though it might be my least profitable account. Everyone in the community knows the church, and I think having that account has definetly helps us land other accounts.
Most of our strange experiences there have been with random members that either volunteer on the grounds, or just want to talk with us for some reason. 1 old guy out there is constantly trying to give me terrible advice about what herbicides we should be spraying, or when we should be fertilizing. He's funny because he's always horribly mis-pronouncing chemical names trying to sound like he knows what he's talking about. Man if they ever listend to this guy they'd have acres of dirt where their lawns used to be lol...
