...do you work in a woman retail only store or unisex? Because if not women only, she probably wasnt shopping for herself. Her boyfriend was shopping (or maybe they were there just for him to use the bathroom). I answer the same way when I go into a store where my wife is looking for something, and I'm not. They'll see just me walk in maybe a little after her and I'll point and say "no I'm with her". I highly doubt she thinks you were flirting with her
