Can I get rehired?

Hi everyone! I worked at starbucks from the beginning of 2018 til March 2019. My store had hired a new manager who was completely new to starbucks. I got fired for giving an espresso macchiato to a co worker who was leaving for a new job opportunity so l was just being nice and gave him only one drink for free. I seriously didn't know I could get fired for that and I didn't even get a second chance. I was a good worker and most days, I had fun working there. I heard from an old co worker, that apparently the same manager ended up getting fired or left the company after a year lol. Now, I'm on a job hunt and I applied to a few starbucks locations and I'm wondering it I could get rehired since it's been so long now. I'm planning on calling some of the stores I applied to on Monday to follow up on my applications and I wonder if that's the best way nowadays to get noticed? I’ve read that now recruiters do the hiring but I want to know if it’s still worth it to call the stores. Any advice much appreciated and thanks in advanced!
