In the late 1970s I worked for a summer as a darkroom technician for the Vancouver Sun - one of the two daily papers in Vancouver. The rules had recently been changed and smoking was no longer allowed in the darkrooms and nearby areas. There were a lot of grumpy, older photographers

.
In many cases, film handling was far from gentle. And the things some would do with prints!!!!!
Of course, we were oriented toward deadlines and the relatively low definition half-tone screens used for preparing a daily broadsheet newspaper with image quality standard for the time.
But even then, when we prepared extra prints for display use or sale to the public, some results were spectacular - there were some fine photographers there at the time.
On the subject of darkroom drinking, I was just barely old enough at the time to legally drink, and didn't drink a lot, but it was certainly part of the culture. There was a wall at the end of the darkroom area that didn't go quite up to the ceiling. The story I heard was that several years later, when the photo departments of the two daily papers were combined in a cost cutting measure (they had the same publisher) the premises were combined and that wall was taken down. Behind the wall they found the shattered remains of hundreds/thousands? of liquor bottles
