As a pharmacy tech, it varies greatly, and depends on your disposition. Best case scenario is working at a hospital pharmacy, where most of your "customers" are going to be other people who work there.

But in retail environments like CVS and Walgreens... at the very least you need to be a very patient person.

Also, I am not making a livable wage, at least not yet. And I am not educated, lol. Though I am in the process of receiving necessary trainings and stuff.
