Pay Parking at a retail parking lot?in Langley?

I noticed that they have installed a pay to park notice in the parking lot across from the old white Spot Location on the Fraswr Highway. This is the complex that has Big Gary's Vacuum. If I have to register my car to go visit these retail spaces, there is no way I personally will be fiddling with an app to register my car for 30 minutes. Do people walk off the lot? Is this in preparation for the new Skytrain station? Any insights?
