The greenish cast is from fluorescent lighting. This type of light has green
spikes in the color spectrum. Your eyes will filter out the green while
indoors, but this is very visible to the film. If you are outdoors, you will
also notice that the lights in office buildings are green as well.
If you shoot print film without a flash, then the lab can correct the green
cast. You can also use a FL-D filter over the lens.
If you are really particular about this, go to Kodak or Fuji's websites,
download the appropriate film datasheets, find out which type of fluorescent
bulbs are being used, and use the appropriate CC filter.
Certain print films such as Fuji Superia, Superia-Reala, NPS, NPC, NPZ, and
Portra NC/VC are designed with mixed lighting in mind.
