I have an old lady that rings me up occassionally, she's a bit far away to just fit her in but the conversation goes "how much to clean my porch carpet 6ft x 4ft?, it's not very big and I want a good job done, can you come today, and I can replace it for a £10", she rings about every 2 months, I have told her that it's cheaper to replace if £10 is all it will cost and that I can't do it straight away.
She probably due to call soon.
