Think in terms of systems. I am sitting at a café as I write this; so what is the “system” by means of which a café exists? What does it need to be able to operate? There are several layers you can look at.
For example; the location. It is a building with doors and windows, with electricity and water. There are tables and chairs, dishes and silverware. It has a coffee machine an oven and refrigerators. OK. How can you use these to disrupt its operation? Jamming the door lock with super glue, breaking the door or window glass, would delay (but not prevent) the café from opening in the morning. This would inflict profit loss in the form of expenses to fix the lock and replace the glass, and potentially loss in terms of busy morning revenues. This is an action that would take less than 2 minutes, and which could be repeated frequently.
If the location could be entered, the chairs, tables, and dishes could be broken or confiscated. Chair cushions can be cut or ripped open. The furniture could be permanently damaged with tar or paint or any assortment of chemicals. The coffee machine, oven and refrigerators could be irreparably damaged; this would actually prevent the café from opening until all of these things could be replaced, and of course, there would be associated costs.
The electrical wiring could be sabotaged, as well as the plumbing.
It is also a given that a café should be hygienic, and this is a requirement which does not need much imagination to think of ways to undermine it.
Their supplies can be poured out, confiscated, or otherwise ruined. The delivery service that transports their supplies to them can be targeted; its trucks disabled, its storage facilities sabotaged.
This is just an example. You can apply the same approach to any sort of business. There are unlimited tactics for the disruption of any company’s operations without resorting to violence.
