The Irrelevant Card Question

Hello. A friend of mine works for Shopper's Drug Mart as a cashier. She asks everyone, including husbands, if they have an Optimum card. The Optimum card can be acquired at Shopper's. Most families have at most one.
I asked this friend why she asks husbands if they have an Optimum card. After all, the question is irrelevant.
Why? Because if there's at most one Optimum card per family, then the wife has it. There's no way she'd surrender it to her husband.
Think of what would happen. The floodgates would be opened. Pretty soon husbands would be asking for their own spending money. Then they'd be buying things wives would deem inappropriate.
Optimum cards are only for the relevant.
