While on the phone sitting in my truck I witnessed a local spray company pull up to a property, guy gets out, puts flag in ground then opens a side door on his truck stands in front of it for about a min. messing with something inside, then puts the bill on the door and leaves. I was half tempted to walk up and read the description on the bill. I wonder what they actually did? Driver never once set foot on the lawn. I just do maintenance so I'm no pro in the fert n squirt dept.
