To the couple of posters that asked why I cleaned them every 2 weeks, it is because I told her I am round every 28 days but she requested I do them every 14 days, I had only been in business a couple of months so welcomed it and the extra money. I also have another customer in another area who requested a 2 weekly clean and it suits me fine.
Believe it or not I have a customer that wants the windows cleaned every week. Apparently where they used to live they used to have their windows cleaned every week too.
95% of my customers are 4 weekly, I have a few 8 weekly customers which I also don't mind.
Back on topic, the rain she mentioned did not arrive anyway.
I will not go back especially for her next week. If she telephones me I will be calm and say, because you have turned me away without warning twice now I will clean you neighbours and if you want yours cleaned you can come out and ask me. I will need payment on the day of the clean from now on though(she used to often say "I have not been to the cash point yet, can I drop it in later?" She never did drop it in later and owed me for 3 cleans 2 weeks ago. Now seems like a good opportunity to lose her or hopefully she will drop me when she hears what I have to say.
On another note, she does have a reputation for being punchy, so yes I will park my car across the street from now on in front of a friend of mine.
