Yep, this is one of the major tells that gives the game away. I was once designing software for a bio-hazard disposal company in San Francisco. "Go-Ware" did everything from dispatching and tracking trucks to weighing the waste they gathered. During the inception I spent an entire day riding in a truck picking up bio-waste in and around the city (do you have any idea how many plastic surgery outlets there are in SF?).

The waste had to be properly contained, gathered according to protocol, logged, transported to the waste site safely, and finally incinerated. It was not as toss and forget operation.
