check this out, did i do a dumb thing? thought i was helping: put a new lawn in in late fall for a customer, lookin better every week, couldnt wait to get there this week to cut, cus i fertilized 3 weeks ago and new this week it would look premo. well, i pull up, and WOW! big brown spots everywhere, the grass is dead! as i looked around, i saw a brown "line", of dead grass , it went from my customers property, right to the nieghbors garage door. now, couldnt help but think someone had a leaky round up container, and left a trail behind them. so i get the customer out and show him, and also show him it leads right to his nieghbors garage door. told him i suspected vandalism, he got mad, told me not to accuse his nieghbor, told me to fix it and send a bill. did i do a dumb thing?
