Being served a warm coffee as to a piping hot one, can happen to any cafe, no matter how experienced or great you are. Out of all of the ocassions this has happened to me all over the world, the staff were fine about it when I asked to be served a hot one, Color Brown were no exception.
Regarding dogs, personally I never bring mine indoors when out in public, he's too big a dog ! I always preferred to sit outside at cafes, as I like to people watch, with the dog having a rest by my side or at my feet.
The owners of colour brown had two little dogs in the shop, is that what you were referring to ?
