They may need them to hunt or for foraging.
so they can get leaves in higher trees
Tourists often have a camera around their necks.
A scarf!!

they have to reach the high leaves
Because their necks are so long, that when they do try to make any noise, it gets lost. One day when they evolve to have shorter necks, I imagine we'll have plenty to talk about with our cousin the giraffe.

Because they might be hiding hickeys or bruises
Giraffes have long necks because their ancestors stretched their necks reaching for food, and this trait was passed on their offspring.
Lamarck would have said that the ancestors of modern-day giraffes had short necks but stretched their necks as they tried to reach leaves in trees; so, their descendants were born with longer necks. Darwin would have said that in a population of ancestral giraffes, some had slightly longer necks than others; the long-necked giraffes were better able to feed on tree leaves and as a result produced more offspring. Over time, the proportion of longnecked giraffes in the population increased.
tourists might wear cameras, glasses, sunglasses, necklaces, passes to parks, and identification around their necks.
The Necks was created in 1989.
