prejudiced

I'm furious at Dillards Longmont, CO.  I dropped off my two daughters to have them try on dresses today 2/23/13 and they were DENIED entrance by the dressing room attendant. The attendant told them that there were no dressing rooms for them.  My daughter said they'd wait for one, and the attendant said they should put the dresses down and they should leave!  My youngest daughter is a high school student who is shopping for prom in 2 months, and my oldest daughter is a mentally [***] 20 year old who is going to SHINE next WEEK!  It is an event put on by the church that is like a Prom party where a formal dress is required.  She's so excited to go and needs a fancy dress.  I think the attendant is prejudiced against my special needs daughter, and that is why she denied her entrance.  I'm mad that Dilliards employs such an irresponsible person, making my daughter feel bad and sad.  My special needs daughter had a credit card with her with her own money on it for shopping, and she had just purchased 5 sweaters with the help of her normal sister. She has a right to try on dresses, too. Boo Dillards!  I can't believe this level of bad taste and customer service.  I told my normal daughter she should have asked for a manager on the spot!  Nasty, intolerant employee.  BOO!
