Worst thing that might happen if someone from HDQ was high or drunk is they might have a few more typos in an email (which the spell checker will no doubt pick up). The most dangerous tools at their disposal are a photocopier or a stapler.
I didnt see a subway station, a taxi cab or a bus anywhere in sight when I was at HDQ but I sure did see a lot of cars. Are you saying its safe to operate a car when you are under the influence?
