What should I do? Advice?

Maile

So I live near a Co-op and I go there frequently but every time there is this one man who follows me around the store and try’s to flirt with me and like rubs my back and arms. It makes me feel so disgusting and uncomfortable. I look much older than I actually am so he may have got the wrong message but still! He looks like he’s 30 ish. What should I do??
