I worked at Best Buy during college, and if you closed you'd have to wait for a manager to unlock the door for you and check your stuff.

If I had to wait more than a minute or so, I'd fill out a time correction for the time I was spent locked in the building. Anytime someone said anything about it, I said if I'm stuck in the building I'm under the company's control, so I should be paid. Eventually managers just started getting there faster when I paged them.

A while later Best Buy was sued for this and lost.
