My wife and I both often have trouble hearing, especially in noisy environments. My hearing level is those environments is much worse than anyone else around. At a bar, I effectively can't understand what anyone is saying unless they're shouting right next to me. With no noise, I have amazing hearing. I went to Costco with my Wife and we both got our ears checked because they offered free hearing checks. Both of us were told we hear amazing, and were subjected to jokes about our marriage. We concluded that their only goal was to sell hearing products, and if they couldn't fix the problem, they didn't diagnose it. I suspect your wife's experience at the "big box store" was the same: Not anything they could fix, so they just sent her away.
