i have a customer that has like 40% zoizia grass, and the rest a mix of our cool season blend. well, naturally, every year, hers is the last to turn totally green in spring, and the first to be partially brown in the fall. well, i went there to mow today, and mentioned to her that i hadn't recieved her fert contract. she said she is not sure what she's going to do, that a popular chain service (i wont mention name) knocked on her door, and told her that HER LAWN LOOKS BAD, cus her current fert company doesn't know what they are doing! that her lawn should be green by now, and it's my fault it isn't. then, offered her a package. i told her, whatever, we been thru this, do as you wish. she says she will send back contract and check, i couldn't care less either way. will they stop at nothing?
