Tips for working at a circle k or gas station

I started working at a circle K 3 weeks ago. I had no idea what it would be like, except I'm a regular at the store. Honestly it was and still is extremely overwhelming. I'm still getting the hang of the register and the routines.. It's the people that make this job stressful. There's a lot of lotto players and folks that come in multiple times a day. I just need general tips and tricks to help me and maybe make my day go be easier
