I'm going to use real names and places here because a) I don't and likely never will work anywhere affiliated with Safeway, b) all this is perfectly public and trivially verifiable information, and c) only by being specific is it likely to make any sense at all.
I'll make it as short as I can... Safeway, in Rockridge (an area of Oakland, California, USA) has a plan to build a new store. As part of the deal with the neighborhood (local activists have been very vocal about objecting to Safeway's plans), they have agreed to provide parking on the roof of their new store, with the following interesting caveats: 1) It's open to all, not just Safeway customers, for two hours, 2) During busy times, they may limit parking to one hour, 3) Safeway will provide and pay for 'residential permit parking only' areas everywhere within two blocks that doesn't have such permit parking already, and 4) During busy times, they will not permit employee parking there.
Question: Where do the employees park, then?
Not within two blocks, that's for sure. As far as I can tell from the news reports on the matter, nobody paid the the slightest attention to where the retail slaves have to park. Few employees of Safeway are likely to live in Rockridge - It is not an inexpensive area to live (I don't live there). Residential permit-only parking either entirely forbids or stringently limits parking time of cars that do not have such a permit, and they're only available to residents of that area.
