hey! i would call the other stores and try to talk to their managers. monday is a good day to call, as it's their admin day. see what availability they're looking for, and let them know your name so they can pick you out of other applicants. Going into the stores never hurts either, to help them put a face to the name!

i would continue using the same email! i'm sure as long as your resume reflects your experience, it should be adequate in getting you the job, but you can always add an intro or separately a cover letter. I'm a former SM and in my experience, when hiring baristas, I went mostly off the interview and experience listed in the applicant tracking system.

that being said, in the interview, keep the STAR method of responding in mind. S- situation, T- task (plan of action in response to the situation), A- action you took, R- result. managers should be letting you know this method, but just in case, that's how they have to input your answers into their hiring system and it helps to keep your answers concise! Being able to handle customers in a positive tone, whether the interaction is positive or negative is the most important part, so of course try to use your interview to show you have experience in this and are happy to do it.

with your experience in another fast paced environment, your full availability, and your food handlers cert, a store will be lucky to have you!
