I've found that some people are also statickier than others, and that 
the shoes they wear make a big difference.  Sneakers are generally bad; 
I suppose a grounded anti-stat mat on the floor would help.  We also use 
anti-static finger cots and an anti-static lab coat for tough cases. 
Yes, a humidifier in the lab room, and a tiny beaker of water inside the 
balance, help a lot if you can accommodate the moisture.  Balance 
manufacturers recommend shielding the sample being weighed in a metal 
container, and we've had some luck with building foil structures that 
are tared on the balance.
