At the time I worked in an ad agency and we did lots of different jobs for our client which was a large company with more than 30,000 employees.

These jobs could include ads, brochures etc. Basically any form of communication between a company and the public and its customers.

Our clients were very demanding, gave us short deadlines after they had sat on the project for weeks doing nothing and were often high handed and rude.

Our contract with them meant that we issued quotes for each project which they had to approve.

For example on a tiny project for a limited mumber of brochures, the printers cost might be $60,000. Normally we add on a 30% profit margin so the cost to the client would be $78,000

But the client were being particularly abrasive and rude and demanding, so we thought fuck them and we just arbitrarily decided to whack on an extra $30,000 rudeness tax bringing their cost to $108,000.

As they were rude and nasty, we did this all the time, saying to ourselves, that person was nasty as hell in that last meeting.

Let's add an extra $20,000 to their next project, so that rude remark cost their company $20,000.

Now this money didn't come out of their pocket but rather their employers but good enough for me.

The account I worked on was insanely profitable for my employer.

We also got bored sometimes so we would decide to catch a cab to the downtown shopping area a few miles away and would always charge the cabs to the client company. The cab forms just included a reference to a job number and no explanation of what for as we used cabs all the time.

The client spent hundreds of thousands of dollars a month on cabs for itself so our little fuck you with the cabs was too small to be even noticed.

After all, for the ad agency and the media agency to go to a client meeting first thing in the morning at the company's offices, meant 6-8 people catching cabs from home to client office and back to the media agency and ad agencies offices, with each return trip per person being around $100 in cab costs. The client company's offices were on the outskirts of the city. So these meetings cost them $600-$800 just on cab costs alone for just 1 of many meetings.

So we stuck it to them for being rude and felt very good doing it.
