Basically i cleaned her windows about 2 weeks ago. When i knocked on her door for payment this morning she said her windows don't look cleaned and was not planning on paying me. She genuinely looked as if i was trying to scam her but i told her that her neighbors saw me and she can ask them. I felt deeply insulted hence my reaction I told her i cleaned them last week but it was actually 2 weeks ago. Her house is on a very busy high road so its possible to get dirty again within 2 weeks. She give me £10 and said its for charity but it just made feel more insulted. Maybe i should have asked for the money earlier but then anyone can say to us "the windows don't look cleaned so im not going to pay you" don't give me that rubbish.
