Give the owner of the lot a call and make sure that it's a valid ticket. There's a lot of scammers out there that will depend on you not doing any further investigation into the matter and just pay the money. I know this because I received a collection notice from Daimond parking with my license number the make of my car and the time and date of the infraction. Unfortunately for them I was working during that time in Poulsbo and was no where near Seattle. A freindly reminder that the proper authorities will be called is usually all it takes if you are in the right. Good luck.
