I have heard countless funny stories about camping misadventures and when it happened to me, it really wasn't funny.
Under stress, the brain releases cortisol which raises your heart rate, increases adrenaline levels and it clouds thinking.
The path to defuse stress lies in tapping into positive emotions. Empathy for the customers situation( which is not funny to them) starts to unravel negative feelings and gives you an opening to start solving problems.
Laugh at the weather, common travel foibles, even lightly poke fun at yourself. Any humor that gets someone laughing has been found to immediately reverse the stress response and make them more flexible and open to problem solving.
As for me, my camping adventure will wait for next year and this time I'll trade my high heels for hiking boots.
