This manager is being totally ridiculous, and he doesn't even realize the full scope of what he did. 

Sticking your neck out for a friend can be risky. In this person's case, they recommended their friend for an interview at their coffee shop job. They figured this friend would be a shoo-in for the role. To be a great barista, you need to be upbeat and positive when interacting with customers, be able to put drinks together quickly, and work well under pressure. U/BAAAUGH was completely exasperated by the way her boss treated that friend she recommended for the job. 

The only person who should be embarrassed by the way things went down is the boss. It almost seems like he's worried that his staffers will steal coffee or something. First of all, most baristas do drink coffee at their workplaces, but it's a cheap item, just let them have it! And secondly, if that's the boss's biggest concern about a potential employee, maybe he should spend some more time behind the counter, preparing orders, and learning what it actually takes to thrive in a cafe environment.
