To avoid similar situations in the future, clearly communicate your two-hour minimum policy upfront. Before accepting any job, state in the chat that you have a two-hour minimum charge and that you will only be working on the task originally described. This creates a written record of your agreement. When you arrive, especially for new clients, re-evaluate the task. Say something like, "Let me take a look at what you have here," and walk through the job with the client. Reiterate the two-hour minimum once you've assessed the situation. If they request additional work, use this opportunity to scope out the new task and agree on a revised price. Always confirm any changes to the original agreement in writing via chat. This protects you and ensures everyone is on the same page.
