    Shift leader shouldn't be training people. He was rude to his new staff, embarrassing them in front of, not just their co workers but also a line of customers watching. However the only person that should be embarrassed is him. He wasn't correcting them he was trying to show everyone he was the man in charge. Only thing he showed is that he didn't deserve the position. Because of his poor leadership skills it made the line move slower. I waited 10 min for 1 ice coffee after I had already paid for it. Point to be made is you get more with flowers then vinegar. Get rid of him and if those kids stayed give them a raise!
