Working in retail or on helpdesk, you see the absolute worst of humanity. It really makes you jaded because you realize just how many comically stupid but insanely entitled people often are.
Not that everyone who calls or uses the helpdesk is stupid (for what I have direct experience with), but even though many have tried I just donโt think itโs possible to defend someone who has used a computer for 15+ years and doesnโt know the first thing about it. No, for the millionth fucking time, you donโt have to be technical to know how to find your Start menu or to know the name of the application you use to do your daily work. This lack of knowledge and comprehension is more akin to someone who has driven since they were sixteen having to be told every time they get behind the wheel of a car what the brake pedal does and how to use the steering wheel.
Retail and helpdesk just expose you to the absolute worst of humanity. No one should have to do more than a year or two in either as both just make you hate everyone.
