    You're complaining about $90k at 30 years old? Give me a break! Wonder why millennials have a reputation for being whiners? Welcome to life. Whoever told you it was going to be fair was lying. ...

    So, you're going to let your supplier determine how to dimension a part they are making for you? I thought the customer was always right. What about the user? Don't they have a say here? Your...
