Prepare to do more work than what you're getting paid for. A lot of pressure is put on SSVs. And just take it day by day, things will be stressful but it isn't the end of the world. Remember baristas are kind of fragile and don't really understand all the things that you have to do or get done. If you get an angry customer just give them what they want and get them out of the store or out of your line. It's way easier than trying to argue. Also Remember to breathe and take all your breaks even if you think there isn't time too. This company doesn't deserve any free labor from you
