Everyone has different workflows... but I would recommend people to at least read one good book on Photoshop or Lightroom workflow before forming their opinion. I have read a few... and most recently this one:

I am an enthusiast, and I don't shoot professionally. So, I don't usually spend 6 hours shooting. But I usually get about 200-500+ frames for each event... like dinners, birthdays, outings. Out of which, I will select between 30-200 of my favourite. I find that I don't lose sleep over post processing. It's very fast. You lose sleep over it because you are prejudiced against it, and never quite mastered the workflow... or your PC needs to be upgraded.
My brother shoots professionally, and I know he spends some time in Lightroom before he sends the pictures over to his clients. He does it even faster than me because he goes through the workflow all the time.
I think the 'dude' who needs the images tomorrow would appreciate it if you would spend some time to process the images before sending them over. My company has hired some of these 'professional' photographers before. They can produce the pictures very fast. However, they never bothered to correct the colour cast, especially indoor tungsten or fluorescent. Tone and/or colour looks like it can be improved with just a bit of work... When we see such work, one wonders if the photographer prefers his sleep over producing good work.
... and it is definitely not true the Oly corrects colour cast better than other brands. My friend with the Oly has this problem... as with all brands of camera. and I can only urge her to do some work with with Photoshop, though I cannot force her. When people say the Oly's colour is better, it is usually for outdoor scenery shots, where the colours appear a bit more vibrant. That's easily achieved during RAW conversion... with very minimal time spent.
