I worked as a soundtech for TV in a far past. The first year all I shot were these '911 shows'.
If you had seen my share of airbags and blood, and on top of that the overwhelming smell of alcohol, you wouldn't either. Or maybe you would, I dunnow.
Although maybe I'm 'lucky', I never took alcohol very well. I am usually way ok with a maximum of two drinks and often am the designated driver.
