It’s easy enough to discuss what could happen under a controversial policy, but it’s a little more difficult to provide evidence after enactment to prove a claim. 

In the case of SeaTac and its newly minted $15-per-hour minimum wage, the proof comes from a single photo of a parking receipt:

Northwest Watchdog called Masterpark to verify the authenticity of the receipt. Kevin, the attendant on duty Wednesday afternoon,confirmed the charge is real. To deal with the higher wage, enacted on Jan. 1, Masterpark is charging customers an additional 99 cents per parking day, a surcharge that comes on top of all other taxes and fees.
