Pull up to do a residential lot today...soon after, a couple guys pull up to the house next to me. The guys have a nice half-ton truck, a first generation 60" Lazer, and some other good equipment. I start mowing on a 60" Lazer as well while my crew mate is trimming. This is a real picky neighborhood, so I'm mowing at about half to 3/4 speed, and laying down real straight stripes. I look over for a see the guy mowing on his lazer at what was def. full speed. He was on a corner lot that wasn't as big as mine, and going so fast that he was literally fishtailing in some spots. I was afraid that he was going to run into my mower or something else. On top of that, he kept staring me down and smirking, as if to say "look how good and fast I am at driving this." Man this guy had some kind of ego problem. I'm young and so was he, so I guess that made it worse or something. Needless to say, he finished before me. My yard looked as good as possible. His yard had scalp marks and uneven cutting everywhere, without any pattern whatsoever. I'm not one to brag about being better, but irks me to see people with that kind of attitude. I just hope he learns what he is doing or doesn't last. I'm betting that the customer won't be too happy, as he used to push mow it himself, and it looked perfect.
