What do you think when you see a woman in open toe shoes without a pedicure?

I've never been one to get my nails done, mostly because I just don't care that much about what my nails look like. But I do walk around in sandals and flip flops all the time. Recently, I started noticing that EVERY woman I see has a pedicure. I don't care about being "fashionable" but when others see me without a pedicure, are they thinking something more....like I'm gross or something? Is this the equivalent of not shaving your legs? Mandatory woman thing? Thanks :)
