Hey @Blueberries ,
Good on you for even giving it a thought.
Do you have much experience with these shops? That is, do you 'know' the drinks? If you are familiar with it, it may help you if you do end up going for a bit of a trial shift like what @Blake_RO mentioned. I guess you can only ask. That's if you feel up to it.
I hear it can be very stressful applying for jobs, especially if you get 'bad vibes' from them.
Maybe it's about doing what feel right for you, so that you can ease yourself into it. But good on you for even giving it a thought.
I'd be interested to hear how things go.
