Quitting without notice (UK)

I just work in retail and I hate my job, I recently got a job at Five Guys which I love more than I thought, the staff, managers etc are amazing. I been trying to work both jobs and been doing 70 hour weeks plus working on my own business but I feel like I’m just holding on to the past and afraid to move on from my last job. I hate the managers, half the staff sucks. The senior managers are on such a power trip with their tiny bit of power saying when we can go.
My question is on Saturday can I just go in and quit on the spot? And like not turn up to work but go in with my uniform in my bag dressed in my own clothes walk up to a manager and say “I quit”?
