Since I'm often in meetings and you can't exactly "chow down" at the boardroom table without pissing everyone off. I rely on MRPs often enough. If I'm in a meeting, I just excuse myself and mix/shake one up. Chug it and return.
People just assume I either just took a shit and came back or made a quick phone call or something.
Big ole sloppy tuna sandwich at the boardroom table sure sounds amusing though! lol!
"what?......WHAT?"
