The Worst Things About Working In Retail

I only work in a quiet store in my hometown, I'm sure other people have worse stories. Please share them!
  1. "Hi, how are you?" *no response*
  2. People who insult your store under their breath
    "Oh... they sell *second hand* clothing"... then they walk out
  3. People who expect you to have the exact perfect thing they were thinking of, then get mad at you with if you don't
  4. When they mess up the display you've been perfecting all day in 10 seconds
  5. When they decide to spend 30 minutes telling you their life story and don't even buy anything
  6. "Can I speak to your manager?"
