oh the times ive seen people at my work try an sell soemthing to an angry customer. It always fails and results in the customer being pissed off and insulted. It should be obvious that if someone is paying you to solve a problem and your software is not working and causing them to complain they are not in the mood to buy another thing to solve the problem they are already paying you to solve.
There are stupid comments everywhere but the reddit user is a unique type of user that is infamous all across the internet.
