A "disruption" fee...lol. I'm sure the college welcomed the "disruption".
Never underestimate the ability of a captive venue to make up fees just to collect more money.
I know several concert and band roadies that were threatened with arrest and show cancelation for some of the most ridiculous made up fees and taxes once someone with money comes into town. This is common in Eastern Europe and other third world countries.
Some of the worst I saw were...
* a social disruption fee for speaking a non-native language in the venue
* a hazard fee using electrical equipment that did not have the local power connector and used an adaptor
* the roaming fee for a cell phones crew numbers jacked up to 100 times the normal cost when using cells in the theater coverage area
* a diversity fee for hiring staff that spoke your language
* a non-standard vehicle fee using a tour vehicle with the sterring wheel facing the edge of the road
And on and on. Typically, it becomes a stand-off with the local Burgermeister Meisterburger looking to get cash, saying we do not have the money, Burgermeister threatening arrest, local tour sponsor getting into a fight with the Burgermeister, a delay in the curtain opening til a near riot starts, Bergermeister paid for something that the local tour sponsor handles and the the band finally taking the stage.
Then there is the equipment "confiscated" for whatever made up reason trying to fleece us as we leave town with it all happening again and this time the sponsor at the next tour stop getting into the drama.
Glad I just code now.
