I used to work in a photo store, one of those 1-hour photo things, around 2002.

Most commonly asked questions were "did you see anything 'weird' wink wink?" Yes.

"did you look at _all_ the photos?" You didn't have to, but the printer running unadjusted was crap since it kind of tried to level the exposure and color tint to some average. I always looked at every pic and adjusted according to how I imagined the photographed wanted it to look like.

Loved taking those machines apart and see how they worked on the inside. Also, for a low-wage manual worker that didn't get a lot of training on the job, one of the chemicals we filled up with from large canisters (for C-46? E-46?) had a warning label it would react with ordinary house-hold cleaner chems and form mustard gas. That was kind of stressful.
