What experiences have you had when you were shopping that were looked down upon by the girls at the counter?
When I bought a necklace, I was looked down upon by the salesgirl, because I might be dressed casually, my hair was not combed, and then my makeup was not put on, so she might think that I am a person with little money, and naturally she would not give me a good look, but under normal circumstances, I will take counter-measures against such people.
