to apologize to the staff for being "rude" and then demand they:

Appologize.
Get competent workers in pharmacy.
Remember customers pay staff salaries.
Be polite to customers.

Most of this issue was between your physician and your insurance company, not the pharmacy. The pharmacy's hands are tied without that approval. I agree that the pharmacy tech should have been a little more compassionate, but I can also imagine that based on your own recounting of the events that you probably didn't give her a lot of reason to be pleasant.

It's good that you took things into your own hands and got it resolved, but as others pointed out, if you were that ill, why on Earth did you spend the whole day at work? And on a Friday no less! We BEG people to go home when they're sick at my job. They do no one any good in that state and no one wants to share the germs!

And just FYI, regardless of whether you think that your consumer dollars "pay their salary," that doesn't give you carte blanche to make a bunch of demands and behave belligerently. Indentured servitude went out centuries ago!
