.... In general, Costco pays and treats their employees better which seems to result in less turnover.
For more important "stuff", it's off to a photo lab.
I've found Costco excellent for 35mm and digital. It does seem that they treat their employees well - you can see it in the interaction of the employees amongst themselves. Think the other big retailers will get the message? Doubt it - it could detract from executive bonuses! It's all a question of mind over matter - They don't mind......and we don't matter.
