Hobby Lobby Stores

I was in the hobby lobby store in Pembroke Pines the other day on my phone texting a friend to ask what it was they wanted me to pick up for them, when I over heard a boy saying "why does she walk like that ew!" I looked over and it was 3 young workers. When I looked at them they screamed and laughed in my face and ran away into the back room. They hid in there for 10 mins until they decided to leave, two of the boys ran away like children and one of the boys who seemed more mature came over to me when I called him over. I told him that it was rude and if they had to make fun of customers to be more quiet about it "everyone has an opinion but it doesn't always have to be heard" he said he wasn't making fun of me but eventually he didn't deny it and just said okay. Later in the store I heard one of the boys saying to another one he was "so scared" cause he's "never been called out for doing that" they saw me and froze and just looked down. Disgusting behavior. It's not even that it's unprofessional it's rude and immature to make fun of another person for anything, especially the way I walk.
