I wouldn't fault her, if that's the case.
The state law, as dumb as it is, has been in effect for some time.
Enough that it's not an issue in common practice with most grocery stores.
Like a female believer of Islam or Christianity, going to work at a strip club as a dancer, then later saying they can disrobe in front of other men.
That they have to do so under a burka or behind a curtain.
Now, the employer can allow this, but the women applying for the job is still an idiot for doing so in the first place, knowing the it is common practice for strippers to get naked in front of other men.
In this case, maybe she should stock some isles or do other types of customer service.
Avoiding the issue entirely.
