Running your own dairy farm in addition to an ice cream factory can have its challenges, not the least of which is cow discipline. Cows are great in many ways, but they can have minds of their own, and keeping them under control and rules abiding is of paramount importance if you want to make your fancy ice creams and whatnot with a minimum of fuss.
That being said, the fine folks at Dairy Princess may not have taken cow discipline into consideration when they decided to on-site their dairy supply, instead they spoiled their cows and gave them whatever they want. As we can see in this example, that's not such a good idea. Perhaps when they watch this footage back, it can act as a wake up call to start giving their bovine employees some structured activities and rules to follow so they don't just go around eating every tasty looking blazer they happen across.
Victoria, for what its worth, is still handling things like a pro. News reporters from other cities need to take note: this is how it's done!
