What a rude thing for someone to say to a customer. Perhaps she should use her brain. She works at a BSS, and most people go to the BSS on wash day. If it is wash day, their hair is probably not looking bouncy and etc because it is time to re-do it....duh. I only go to the BSS when I am looking for something to use on my hair that day, i.e. when it is time to wash my hair. Now, my hair doesn't look horrible when I go, but it is not looking like day 1, freshly washed and styled hair either...lol. If it isn't looking presentable, I just comb it into a ponytail and wear a baseball cap.
I have seen other women come in there with their hair all over the place though, or wearing a conditioning cap, head scarf, du-rag, or satin bonnet, or rollers. I've never done that, but hey to each his own. After all, they are coming there to pick up products to help them do their hair, so at least they are trying to take the steps to fix it.
I think if anything, you should complain to her manager because offensive comments like that are bad for business. If people are uncomfortable shopping there, they won't come back. Any manager would want to nip this in the bud to ensure they won't lose customers. I say call the manager. The woman needs to know she can't say these kind of things to customers. I mean, does she ask the black women with dry/brittle hair what African tribe they are from?? In her mind, she might think that is okay to ask as well. And Lord knows she might get pimp slapped if she asks a sister that question.
Call the manager...
