So when it comes to difficult customer interactions, I've had this quite a bit in the past, but usually I just keep my calm, keep my demeanor. A lot of the times if there was escalations within the customers themselves, I just would not allow it to affect me personally because a lot of that kind of stuff doesn't affect me as a person. And I just try to be calm, be patient. I try to convey with them like, hey, I understand your feelings. I understand this might be a frustration, but this is what I can do. This is the best I can do for you. And it's just always about keeping a calm demeanor, no matter how they escalate the situation or on your kind of end. It's just how you go about it in your own kind of practicality.
