You can't without permission. I work a grocery store before starbucks and I'm not allowed to work that stores starbucks because it's a different coffee shop. Unless you don't want to ask and hope they never find out.
Grocery stores buy the rights to have starbucks products, they are not starbucks themselves if that helps distinguishing why you can't technically work it.
They also aren't the best cause there are a lot of times there is one person the whole department and the store will refuse to shut it down or turn off mobiles
