Got a "Can you clean mine today" a few months ago.
Cleaned, knocked for the money "Can't find my purse can you call back tonight? I'm in every night after 6."
Called twice - two nights, no one home, finally caught her on the Saturday.
"I've called twice like you said after 6 but there was no one in."
"Well, the windows weren't cleaned properly anyway, they were all streaky.
"What, even when they dried off?"
"Yes."
"But they look O.K. now, there's not a mark on them, look at the difference in the frames, and all the bird muck has gone."
"Well they weren't cleaned properly."
Working today over the road - head out of bedroom window caked with bird muck "Can you clean mine today?"
Bad enough - then she added "And I'll pay you next week."
