I use light controls to deter the amount of theft going on in my room by my employees. I use some mood lighting to give my room a comfortable feel so my customers know that it's safe to come in and relax. I think that you should consider lighting areas of your main walkways to drive traffic away from your customers and the residual light will create that well-lit atmosphere that customers desire.

If you have a restaurant/food area, you should light it a little more too because customers like to see what they are eating. That will spill some light into your room too.
