ok...got this seasonal who called to have his drive plowed (3" trigger, we got maybe 2"). my contract states "your driveway will be plowed for any snowfall of 3" or more...blah, blah, blah...i don't have anything in it that specifically says you'll be charged extra if you call to have it cleared w/ less than 3" (opps!?) i know that's what i meant but i'm not sure if i should charge for it or not? it's implied but doesn't really state it. what's the right thing to do? is it my mistake? i did put it in my notes for next years contracts!
