I am pretty sure that 90% of my worst days working took place when I was with Enterprise Rent-a-Car after college. While the job itself was not the worst, the people that I worked with with demons sent straight from hell. Every single on of them had the “I have a degree so I am smart” mentality and felt entitled. Not to mention the ABSURD customers that would complain about the most obnoxious things just to save a few bucks at the end of their rental.
While many of those days were a personal hell, they don’t even come close to the worst days that these folks had at work.
