Here's the deal. I had a one-off booked. Private event. Spent 2 hours making suggestions at the venue with the client. All is good. Contract signed, etc. Total was going to be around $2,500, less some expenses and additional labor. Client calls today and wants to cut 90% of the rental, basically making it not worth my time to even drive to the venue. Should I just tell them it's not worth my time, or should I do what they want?
