Unacceptable service

Disgusting experience at Seattle Boksburg. We were assisted by Trudy she had a bad attituted I've asked for 2 butterscotch steamers without her starting with it I've canceled one because my fiance did not want steamer but cool drink instead. She rolled her eyes and screamed at the cashier to cancel one butterscotch steamer. She made me a butterscotch freeze instead of a steamer. She made a mistake because of a super disgusting attitude.
