How to quit a part time job after 3 days respectfully?

I started work for a fast food place. Day 1 I just got thrown into the pits, barely anyone was assigned to train me, almost messed up a few orders. Had to go around asking for help all the time and it felt like the other employees thought I was irritating for even trying to reach out. Felt like the manager didnt know what to do with me honestly. Day 2 and 3 I got a little more help throughout my shifts but basically just left scrounging to either find something to do or just staying out of the way. There's another job I can start the next weekend (during this jobs day I dedicated too) I want to quit immediately, how do I do it respectfully?
