Just for a slightly different perspective here:
You're John Q law-abider and have jumped through the labyrinthine hoops of not only the People's Republic but also UC Berkeley to satisfy all of the draconian regulations and obtain all of the necessary permits and certificates etc to be able to sell food at a campus event. You've paid the Univ their blood money to do business on campus. Wouldn't you want someone protecting your financial interests? Would you want me to be able to compete with you pulling a crockpot out of my trunk with basically zero overhead and food safety? When your kid contracts Listeria and is fucked for life are you gonna find Juan and determine the source of his contaminated food? How would Berkeley go about doing that?
Now, UC Berkeley is total and complete bullshit, and it's fucking ludicrous that they direct their officers to allow violent communists/anarchists to intimidate other students and burn the campus. It's fucking bullshit that they ban speakers in the name of tolerance. It's all bullshit, and yet they instruct their officers to enforce unlicensed vendors? Because that shit is money they're not collecting in permits. However, I've been in situations where I was instructed to let motherfuckers throw bottles at me, but to give zero tolerance to bullshit offenses.
