Man, that's brutal. Twelve years is a long time to be doing it wrong.

You ever try counting to ten with a dog that's barking nonstop at the vacuum cleaner? Doesn't really work, they just keep going. But yeah, that pause trick helped me with a customer who was furious about a groom that came out patchy. I counted, took a breath, and realized she was actually upset because her dog had mats and we had to shave them off. We talked it out and she left happy. The counting gives your brain time to see the other side, even if it feels weird standing there silent for a few seconds.

Damn that sucks, hot milk all over your laptop sounds like a total nightmare. Tbh I've had a cheap gadget die mid-demo too and it makes you feel like a total clown in front of everyone. Good on you for rolling with it, at least now you got a story for the coffee club.
