A Clear View Window Washing

I hired Richard twice and he did an awesome job of the windows! No complaints there. He can be both friendly and helpful. But, he can also be quite abrasive. He spends a fair amount of time complaining about other customers (people who don’t offer him a cup of coffee, people who ask for an estimate first, people who expect a prompt call back etc, etc, etc). During his second visit, he was on my porch when he opened the door and asked if I ever wanted him to wash my windows again. Confused, I said «yes.» He then proceeded to say that we needed to set some ground rules. «When I knock, you come.» He had apparently knocked on the window, which I didn’t hear because I was dealing with a 3 and 2 year old who fighting over a toy. Both kids were screaming and the yelling continued while Richard was talking. And… as it turns out, all he wanted to know was where I bought the grapefruit juice I was drinking. I hired him to clean my windows, I made him coffee, I don’t mind responding to knocks on the window. But «I knock, you come» is disrespectful and patronizing. I’d rather have dirty windows
