over the years ive had a customer here and there tell me to just do "whatever i think needs to be done", and send the bill. well, this year, ive actually had about 6 or 7 clients give me that speach. they say while u r here mowing, if u see something that should be done, no need to ask, just do it, and add it to the bill. now i have never actually done anything without discussing it with a customer first. wonder how it would go over if i took it upon myself to aerate, and maybe trim some branches away from the house, and tack on $250 to the bill. any of you had customers tell u this? how did it work out?
