All the more considering the apparent motivation and justification for such a law—that it is "an indignity" for customers. If such a reason were to be seen as valid, what would be stopping a law that for instance banned customer-facing workers from wearing facemasks due to the resulting "indignity"? I'm hardly a free-market purist, but this is a prime example of a let-the-market-decide problem. Let businesses decide if they need bulletproof glass or not, and let customers decide if they want avoid the bulletproofed stores if they feel affronted. One may argue of course that, given the choice, all stores in certain areas would chose to install bulletproof glass, leaving the customers with no choice. If that were the case then surely the problem is much broader in scope than customer dignity.
