Wildlife Safari also makes their elephants perform other tricks like "dancing," in addition to washing cars, and they also allow visitors to pet the elephants and take selfies with them. This past December, the zoo sold tickets to a "Christmas extravaganza" in the elephant barn, where guests could get an elephant to paint a wooden ornament for them.
Yet Frohoff doesn't think elephants would be doing any of these things without the threat of bullhooks - long sticks with curved, sharp ends. While zoos often claim that the keepers only use bullhooks to guide and "train" elephants, the pointed end can break skin, and some keepers have been known to use bull hooks to beat and torture elephants.
In a recent video on Wildlife Safari's Facebook page, a keeper appears to hold a bullhook under his arm as a visitor proposes to his girlfriend in front of the elephant enclosure, while onlookers snap photos. The keeper in the video of the elephant car wash also has a bullhook tucked under her arm.
