We gave that to her and she walked out. She then walked in and asked WHY IT WAS SALTY. She went onto explain that it usually tastes sweet and that she's ordered it before. We told her that she ordered SALTED caramel cold foam, and we put salt in it, because it's a SALTED caramel cream cold foam. She argued with us, but we didn't give her the wrong drink, so she walked out with salty foam.
