What’s a “dead drop” – to secretly pass an item to someone, without having to meet with them directly.
How it works – I deposit the item in a pre-determined location, then in another pre-determined location, leave a signal that I have done so. Maybe this signal is a chalk mark on wall, or I hang a pot of red flowers on my balcony.
What if the dead drop was a supply closet, inside a bathroom, inside a retail space?
Both genders could enter without arising suspicion, and there cannot be cameras inside a bathroom.
Would an employee ever find a USB key in here? Nope.
