Green bean starting on Monday

Hello, I just finished onboarding on Wednesday and start my training on Monday. On Wednesday I got a tour and met some of the baristas. They were nice but it was only 3 of them and i don’t know if those are the same people I’m gonna see Monday. Monday I also meet my trainer as well. My store is drive through and immediately when I was shown the register and drive thru I was like uhhhh idkkk bout thiss but I’m sticking it through 😭. It also was crowded and I just like 🫣😳🫠 am I really gonna be able to do this? Ik iam but the beginning for me is always rough especially being shy. I just hope I’m gonna be able to mingle with everyone good and eventually get comfortable. Any advice for someone like me is greatly appreciated lol😭
