as far as i've been made aware, there isn't a differential for Starbucks anymore; it's just PG35 across the board. $13 minimum for everyone
why not? service and engagement actually owns the guest experience at starbucks (no wait, friendly guest interactions, etc) so having more front end people who know how to ring is definitely a good way to get started with that. definitely bring that up to the TL/ETL who won't let you train the person on register. the actual operations (making drinks, food, etc) is still general merch/food, though.
-----my STL told her no. Didn't give a reason. I told her its prob because she's too much of an asset to guest service.
there's no reason that starbucks can't backup cashier if they've got the coverage and it's not very busy. but that's very rarely, if ever.
