these guys are great, wonderful, excellent. but sometimes they are TOO GOOD. first of all, they have a habit of weedwacking "wall to wall", what i mean by this.., ok it's hard to explain, they go around the entire perimiter of the property, even the areas where i AM ABLE to get with the mower.let me give an example: when you have beds, and you can get to the edges with the end of the mower, why do you need to weedwack there? this takes more time, and beats on the crew,the wackers, and, it's unnecesary. also, we edge every other week, WITH A REAL EDGER, not with a weedwacker. but i am CONSTANTLY having to tell them not to edge with the wacker. they seem to think every other week with the edger means, on alternate weeks you do it with the wacker. now, when i tell them to STOP, and follow the instructions they were given, they get an attitude, and start doing a bad job wacking (missing areas that need it, etc). i understand they just want to do an a+ job, but the job still is a+ if you don't wack every edge. it drives me nuts when they "flat top" every edge. for the life of me, i don't know why people go around the edges of the walkways and "flat top" the edges. it looks stupid, and is time consuming. these guys are so good, that if i tell them i don't want it done like this, what they do i move that much faster, to still do it, but be within my time frame. input?
