Wag don't need to add anything more than that for us to know they care more about a very small amount of money than the dogs customers entrust to the care of the walkers they employ.
To be honest the money is actually a small and distracting aspect of this story. If it was my dog I'd want to know what happened. The fact Wag won't give any proper answers shows they probably don't know what's happening to dogs people trust their walkers with. That is a HUGE problem for me.
No, you don't. You only have someone's claims about Wag's side of the story.
It sounds authentic, but Internet is full with authentic-sounding false stories.
The principle of Occam's Razor applies here.
And no, Occam's razor does not apply.
Everything in the world is a matter of understanding the marginal impact. There is no universe in which hearing both sides of the story (or trying to save n number of dollars) results in a better net outcome for Wag as a business than apologizing profusely and visibly showing as much empathy as possible.
