the customer keeps asking to mow shorter. i already mow the warm weather grasses as short as reasonably possible--yet i have customers that ask for it to still be shorter. unless they have a perfectly flat lawn, this always means scalping. even when i point this out, they still ask for it. i think it's because they talk to their friends who tell them bermuda can be mowed at 1"--so armed with this bit of "knowledge" they all of a sudden know more than i do about their lawn. it's amazing.
