Pfizer would have done it and you'd have to take a test when it was over and get a 90% and the report would go to your DM.
This was a touchy subject when calling on offices. A couple of times while waiting in the nurses station, I felt the urge, asked for the key to the restroom outside in the hall and would get a cheerful, "Oh just use ours!"
Then you had to learn how to time a fart so you could let it fly when no one was around, the samples were in the closet and you could slam the door and start walking just as the sound barrier was broken and before anyone could get back there to ID the culprit.
Those were the days.
