By a table with several boxes and two coffee cups on it, a woman in a green sweater is opening a small box and another person (whose head cannot be seen) is operating a small handheld electronic device.
A woman opening boxes while her colleague checks a shipping manifest.
We have no idea if the woman checks a shipping manifest or what she is doing. There are alot of electronic devices.
The man does not have to be her colleague. What is on the electronic device doesn't have to be a shipping manifest.
Although there are two people, it does not mean they have to be a colleague.  An electronic device does not mean they are looking at a shipping manifest.
