Yes, so as a manager, this has happened a handful of times. One particularly I remember, this lady had come in, she was unhappy with how her bowl had been prepared, and that specific day that she'd come in, I wasn't there, nor did she ask for a manager. But she left, and then the next day, my coworker was telling me, yeah, there might be a complaint from this person, she was pretty upset. And sure enough, that lady had called back that day, and she was demanding that her meal be replaced because she didn't like it, she didn't even eat it. But at the time, we'd had a policy that was if you call back the day after, we can't really do anything for you. You have to call the day of, or tell us right after it happened, just so we know, so we're not just like, well, who are you? We don't have any way of looking you up, because a lot of these times, people don't keep their receipts and stuff like that. But yes, so we were on the phone, she's like, well, I come in there all the time. Which I'm in there all the time, so maybe she was, I don't know. But I didn't see her before. But she's threatening all this stuff, she's like, I'll post it on social media, and whatnot. And I'm like, okay, well, I told you what we can do for you, we can give you da-da-da-da-da, is that good enough for you? And she kept being like, no, that's not good enough for me. And so she was just being rude the whole time, and then she was like, what's your boss's email? So I gave her my boss's email, and she was like, all right, I'll get in contact with him. And I was like, all righty, have a good rest of your day. The whole time, just being professional as can be, while getting threatened. But my boss, thankfully, was always on my side and always had my back, so it went well.
