"see-ya...BYE!"
I've only given 1 or 2 weeks notice twice in my 30-some years of working. Once, I got fired on the spot, tghe other time I was asked to train my replacement...which, for a crane operator, can be...awkward. Crane operators SHOULD know their job before they get dispatched...fortunately, the union hall sent a decent replacement, and all I had to do was show the new guy a few of the ropes about the particular jobsite, the barge, and some tips about working on the water. My last week was pretty simple.
OP, sounds like you did things right, and the meeting went well. Sometimes it's tough to quit a decent job, but often you have to as a career step.
Good luck to ya.
