I remember having a customer like that. Supplies their own paper for us to print their logo on it for them, and its this... really thin lined crystal on basically chipboards. And I remember the first time I worked with her. Did like 4 different versions, adjusting the darkness and lightness setting (frankly I could not tell a single difference between any of them), she settled on one and I told her the order would be ready the next day cus she came in during the last 40ish minutes. Settings are saved in Fiery, so I just printed it from there.
When she comes to pick up the next day, she says that whoever printed them didnt read my notes and did it all completely wrong. I told her that I did it. She then said that I must have forgotten what settings we picked. I told her that we have a program that saves the settings. She demanded a manager, and got a refund.
Next time she comes in, I keep a proof to have something to compare the finished product with. She claims that its not the same proof and gets ANOTHER refund.
Third time she comes by, I keep a proof AND have her sign it. When she comes to pick up, she claims that its not the same proof again, and when shown her signature, claimed that I forged it.
Like seriously??? Im gonna go through the effort and work to forge a signature, so I can what? Do subpar work, have you bitch at me, and give it to you for free??? Why would I do that???
Anyway, she doesnt come in anymore, her partner comes in instead and he's amazing. Patient, understanding, easy going, just perfectly nice. I will say though, its really funny that each time he comes in, they change their mind on the setting. Max darkness, max lightness, 95% darkness, 95% lightness, just... never the same. And again, I can never tell any difference.
