Oh? How do we propose to administer this program at the top level and proctor the tests at the ground level?
For short term storage, airport-style pay lockers are an option here - put X quarters into the locker, take the key, then upon re-insertion the key is held captive. No per-transaction administration required, however someone might have trouble on occasion and need real-time assistance.
Not necessarily a bad plan for the small paid storage option that we’re proposing, but one suspects that there are cheaper options out there than ULINE.
