This is good advice- I just quit my job by leaving a note because I wanted to give enough notice and neither of my managers were at work. I thought to myself how I should be doing it in person at the time but now I realize it went smoother that way

I wrote a letter out stating my last day, explaining why I was leaving and thanking them for employing me for the last 11 months. It felt so nice to hand it to my manager that treated me like shit. He glanced at it and said "well, you can have today as your last day" although I had booked that day off, and it was payday the following day. I was more than glad, however it might've been easier if I just spoke to him.

I was going to say, lol! OP must not have spent as long as they said considering the most "professional" way of quitting.

At my last job when I gave my two weeks resignation letter, I went to do it in person. I gave my boss my letter but he gave it back to me and told me to send the letter through email.. so it really depends on the job and your boss's preference... but I do agree with you. Generally, always do it in person.

There is nothing wrong with a letter of resignation being sent via email. It is still documented and can be sent to all necessary parties at once (supervisor, GM, HR etc.) especially if it is a company that has its main office in another city. I have always brought a letter for my direct supervisor, and emailed the others. This way no way can deny that you gave notice.

Exactly what I was thinking, you spent hours deciding on a professional solution for quitting your job and decided calling to quit on the spot was the best solution? Kudos for the courage, maybe working on your decision making skills.

A lot of places require notice in writing. After all, docs or it didn't happen. ^_^

and never in ALL CAPS ! ;)
