It's a very, very rare thing for me...but I got to file a lien today.
The transmission shop featured in the thread "Auto Shop Horrors #2" never did get around to moving a few cars, so I could finish the job. Then he got in a squabble with his landlord, and got evicted.
The landlord, who is quite a piece of work himself....will now find I have a lien on HIS property. I think he "out clevered" himself, in his attempt to sucker tenant into paying to modernise his property.
