If you would like to do something to help them, you might try printing out a care sheet and giving it to the pet store. It may do nothing, but they may listen to you/the sheet and try to make the animals more comfortable. If they're not sure what sex they are, and are not willing to try looking or aren't sure how to tell, but they are willing to separate males from females, you might either take in a picture of male vs. female to show them the difference so they can check, or check yourself.
Here's the care sheet that I gave copies of to a store near me that has a couple of hedgehogs: http://www.hedgehogwelfare.org/HWScarebrochure.pdf I also wrote down the websites for this site and the wiki site on each of the care sheets, and wrote that males and females should not be kept together.
