You can dial back the drama a bit. Nobody said anything about back breaking labor. The fact is, people often DON'T include their address when paying with F&F.
When I package and ship ten packages in a day and one paid F&F but didn't give me shipping info, it's an inconvenience for me when I'm geared up to do shipping and a PO run. If I have to message them and wait for a response, it causes me some headache and costs them at least another day or two of waiting.
If you're day is simpler than that....good for you.
Take your argumentative, eternally contrarian opinions on PayPal fees and taxes somewhere else. That's not the point of this thread and I couldn't care less about your opinions on that subject.
