"Base Supply?" Was this a "store" on a military base?
At Air Force bases, there's always something called "the LP Store," which used to stand for "Local Purchase." It's where you get everything from letter openers to staplers, paper to shredders. Office and cleaning supplies, just about anything that you'd need on an "as needed" basis. Usually attached to this is the "Individual Issue" shop, where uniform items, boots, web gear and so on are issued. All of this stuff is handled through the Government Purchase Card program-it's a credit card that is for mission supporting items. I have outfitted offices with reams of printer paper, mops and buckets, calendars and pens. And I've outfitted scores of troops with safety boots and almost a dozen airmen for deployments to the sandbox and other places, all through Individual Issue.
You can wander in and browse any time of the business day. But the key is that you can ONLY buy with a Gov't Purchase Card. In other words, this store is for BUSINESS (DUTY) PURCHASES ONLY.
It looks like a store (at Lackland AFB it's operation is contracted to a National Industries for the Blind organization), but it's really just an extension of the Supply Squadron.
Is this what you were talking about?
