Why would it? Costco is not going to hire more people simply because they're putting liquor on their shelves. They're not expanding the square footage of the store, they're merely substituting one product for another. They'll add liquor and reduce some other product's presence. Same with every other store.

The distribution centers will likely absorb the laid off government workers. The delivery drivers will simply make more stops each day on their routes.

Additional hires will be negligible.
