Discrimination

Discrimination-noun
the unjust or prejudicial treatment of different categories of people, especially on the grounds of race, age, or sex

Had a new one recently...If a company advertises a 3-month supply as $10, is it $10 regardless of quantity? If not, is it a discriminatory practice to charge more?
Without an asterisk to explain *typical 90-day supply, this is misleading. If someone takes a medication once a day and another patient takes 4 tablets a day, the quantities are quite different, yet the day supply is the same.

It is no different than explaining the car companies are not discriminating against you because you bought a truck with a 20 gallon tank and the little economy car only has a 12 gallon tank. Sure, it takes more gas to fill, but it's not discrimination. You're not sicker because you need a higher dose. 

A guy pulled out his phone and wanted to record our conversation. He was accusing me of discrimination on the grounds that he was "sicker" and needed a higher dose than the average person. He threatened to sue me and my employer. Medications come in different strengths, dosage forms, durations of action, etc because not everyone responds to the same medication the same way. 

Do bigger clothes require more material and are they more expensive?
Bigger turkeys weigh more and cost more. If you're feeding a family of 20 for Thanksgiving, is it discrimination because you require more food to feed them than a family of 4? 

I'm not sure if the novelty of his argument surprised me or just pissed me off for the insane logic behind it.
