Transcript for What Would You Do?: Mean Barista
Reporter: We're back at the fine grind. I need a triple shot, chai caramel latte. Reporter: -- Where we let a rogue coffee connoisseur ruin everyone's day by ordering a very complicated cup of coffee. That's not my order. Get it right this time. I understand. Reporter: But what if we turn the tables? Now, it's not the order that's difficult, but the server behind the counter, like in this "Snl" skit. This is tea, I ordered a latte. Okay, so one tea, one latte? Why she ask for a tea if she wants a latte? I don't know, man. That's stupid. Reporter: We replace that machine with the real deal. Can I help you? Can I get a medium decaf coffee? Like, that's a ridiculous order. Reporter: Nothing they order seems worth the effort. If you had to deal with this barista from hell, what would you do? I'm edina, and I'm playing the mean barista. Small, iced latte with vanilla sugar-free syrup and skim milk. That is way too much information, I'm sorry. Yeah, I'll tell you what. I'm going to give you a piece of paper. It's just a vanilla iced latte with sugar-free syrup. I just want to make sure I get your order right, because I don't want to see you complaining later. Write that down here. Reporter: Right away, she takes the self-service approach. Okay. What is it you ordered again? You made me write it down on a piece of paper. Here it is. Okay, we're good. I'm sorry, it's been a long day, y'all. I have been here forever, I'm so exhausted. I started at 7:00, you know how long that is? Making coffee after coffee. Yeah, I know, I gotta get back to work and I started at 7:00 as well. See, but you get to leave. I don't get to leave, I'm just stuck back here. And you probably get paid real money. I'm getting nothing compared to what you're getting. Like, it's exhausting. I'm going to cancel my order. Reporter: And with that, this woman has had enough. All right, cool. Reporter: What did you want to drink? It was sort of a hard order. It was just a latte. Reporter: How would you describe her behavior? Obnoxious. Reporter: This woman can't believe what she's seeing. She's berating this woman. Ma'am, can I get you something? She was like, what do you want? Give me a second, I'll see if I can figure out what's going on. You're saying I'm not good at what I do? There's no ice in the coffee. Because it melted. Reporter: Did you have any second thoughts about confronting her? No. Reporter: Why not? We have to help each other, we're all going through this life. Walking the same path. No reason to be like that. Reporter: We roll one last time, and she's right back at it. You wanted hazel nut, didn't you? I just wanted a plain iced coffee. The attitude that you are giving is f'ing ridiculous. I am not giving any attitude, I am just trying to give you guys what you need. He made a crazy coffee order and I'm, like, trying to give you guys what you need. Where is the owner, is the owner here? What, like I'm not good enough? No, you're not. I want to see the owner. Why, is there a problem? He asked for a complicated order, it's a hot day, it's been a long day, I'm trying to -- Iced coffee not a complicated order. It is if there's no ice here. Reporter: Jason is done. Are you implying that I am stupid? No, I'm not implying that you're stupid. I poured coffee in a cup for him, right there for him, and he's still not happy. I just told you there is no ice. Like, if you had made the coffee at home, you'd have ice right now. You have no ice right now? No! So you can't make me an iced coffee? That's what I'm going to order. Well, he just asked me for an iced coffee, and I couldn't do it for him. Do you have any ice back there? Reporter: Unfortunately, this woman is out of luck. There's no ice back there just a camera crew and that guy from "What would you do?" Oh, my god. Oh, my god. Reporter: You were getting a little aggressive with her? I wasn't getting aggressive, I was frustrated. It's unreal, I've been coming here for two years and to see someone get treated like that, it's a little frustrating, yes. I'm so happy that it was not real. I can't believe you kept a straight face. Reporter: It turns out that today, the most popular thing on the menu, whether you're a customer or a barista, didn't really matter. Just, please, hold the attitude. Be sure to catch us again next
