Here are my photos:
Parking lot:
Automatic WB:

Daylight WB:

Fluorescent WB:

In this photos, for my surprise, the automatic mode reflects best the scene while the daylight mode gives the photo a yellowish touch and the fluorescent one gives it a blueish touch.
Shopping centre:

I this photos I can't see a lot of difference between the automatic mode to the fluorescent one but I do like the daylight mode as it's not so glossy and gives a more warm feeling for a cold place.
Covered market:

Fluorescent WB:

The fluorescent mode probably reflects the real colour of the scene best, but again I love the yellowish daylight mode.
We can see that if you take a photo of a florescent lights in a daylight mode it will turn the white bits into yellow, so if you intend of making a photo that don't reflect the reality but try to make a place warmer you can use it, mainly in public places you wish to make more 'homey'. I think that the best place for that will be in a labor wards in hospitals. making a photo of your new baby under a florescent light. Well... I'll try it in my 3rd...whenever that will be!
