I have a friend that was mowing lawns the other day and at the end of the day got a couple of phone calls from his customers saying that after he finished another LCO knocked on the door and offered to do the lawns for half price next time ( with out knowing the price) one lady played along and asked a bunch of questions insurance? (ABN no. aussie business no.) she got his ABN. turns out its his mobile telephone no., my friend noticed the bloke parked further up the street a couple of times, what would you do now???
