3 weeks? not even. my official training lasted 2 weeks, and I just didnt know what I was doing for about 4. my manager went awol, and another sm in the district dual managed us, which worked out in my favor bc he is the one that "trained" me, my training was basically 3 shifts at a well run store, teaching me how to make capucinno, lattes and coffee and americanos, how to grind, how to do small tasks, run POS, so I had 3 shifts there in total... One running register, one on bar and one floating... and then I was sent to my home store after each shift to try an open, mid and close.. it was GREAT! but then partners from other stores came to my store and helped drill me on learning the procses, which was great bc my partners didnt care at all, so when the borrowed people realized i cared and wanted to know, they helped me through the process, and it turned into a successful although painful and drawn out learning process... Even up to this summer Ive still be realizing ive done things wrong bc i simply never learned how to do it properly...but at least I care enough to figure these things out.
