Pros
Great idea. Customers who actually try the product tend to like it and stay loyal. The fuel drivers are a great crew--they work hard and enjoy taking care of the customers. This is a great job for people who would normally be driving 7 days a week with few benefits and not nearly as much excitement as what you see in an early stage startup.
Cons
From a high-level, this is a gas delivery business. And that's just not very exciting. Internally there are lots of problems. Sure, every company has petty stuff going on. Cliques and drama. Unfortunately, in this place, the CEO and other leaders ("leaders") take it to the next level. They listen to the wrong people, both inside and outside of the company. They never have your back, and everyone is replaceable. In this negative environment, lots of people quit or get fired. Just search LinkedIn for all of the dead bodies left by the road. You can't have that much turnover and not have major internal morale problems. People don't leave jobs, they leave people. And this place has a major people problem.
