The Red deer at Longleat Safari Park in the south-west of England are not tame. They are wild animals, it is just that they know that the visitors come with food. The visitors buy cups of pellets at the little stand, and park on the grass. The deer know that when a cupped hand comes out, they can eat. Once the pellets run out, the deer move away.
The pleasure for us is the opportunity to be very close to a deer.
