I took my chl course just last month. The instructor told us that a 'gunbuster' sign serves as effective notice only to the employees of a business that posts such a sign. In other words, If your place of employment posts a gunbuster sign, you can't carry there. (giving notice in the employee manual or during new employee orientation is also sufficient notice regarding prohibition of guns in the workplace). However, any customers who enter your place of employment can legally carry, assuming they don't have a 30.06 sign posted as well.
