Generally, the women who are on their feet more (service industry jobs, servers, retail associates, etc.) will be more prone to willingly receiving them, as there's a reason to get one. Some will tend to have some sort of self-conscious resistance, for whatever reason ("No, I've been on them all day, and they're sweaty and gross," or "I'm self-conscious about my feet. I think they're ugly and don't like people touching them," etc.), but if their feet are sore, it's not hard for them to overcome their apprehension.
