I don't mind, as long as the said people ask before they dole it out, and if the dogs have to do something first. Usually not complicated, a simple "sit" or "shake" will do.
Flicka will happily accept treats, pets, attention, anything (Seriously, the dog is starved.) from anyone that's willing to give it to her. Pepe, on the other hand, won't accept food from strangers, so not really an issue there.
