I have.
A customer put me onto a friend of her's who wanted her windows done in the summer.
To be fair, she knew I was single now, but it was a window request.
I went over, did the windows in 15 minutes and was there 2 hours.
I went out with her for about 2 months.
She was pretty tidy actually, but I just got bored. Rebound I guess.
I still "pop round" from time to time...

Oh, and actually my ex who I was with 10 years I met while cleaning a pub.
