I recently had to fire a customer. The money they were paying me was not worth the headache they caused.
I'm looking to branch out and work with people who are relaxed. Let me know your customer persona or your dream customer. Want to find people I enjoy working with.
One idea is to try to learn from other startup playbooks, using knowledgebase or chat bots as a way to help customers or users to help themselves. But you have to set that expectations very early when the user sign-up and that they are well aware of the limitations for technical support.
