After entering Starbucks, the company will make you a "partner card" with your job number and name on it. You need to show your ID card and other documents to prove your identity before you can use it.
But generally speaking, if you want to buy something, you will buy it in your own shop. If everyone knows you, you can enjoy the employee discount without showing your ID. If you need to show your documents, you will usually go to other stores, and others don't know you. You need to prove your identity.
4. The employee card can only be used by yourself. If you are found to have lent it to others, you will be warned (it seems to be a warning, which will affect your promotion anyway).
It used to be less strict, just report the job number, but now it's more strict ~
