I think I'm at the end of my tether with customers right now, I really do.
We have a large catalogue of designs, some created by us, others by well respected artists, some licensed well known paintings and so on.
First I get a complaint about a well known painting I printed onto a product. Customer states that whilst it's only a small issues it detracts from the design, they'd like to return for a replacement. No problem at all. I receive the product back and can see the issue. A small brown mark, measuring less than 1mm in diameter. I check our designs and the spot has always been there. We've sold 1000's of this over the years but I guess you can't please everyone! I edit the micro-spot and reprint, job done.
Now, a customer complains about one of our designers images. Looks like it has a pen mark on it? I check the customers image and there is indeed a black line, 3 maybe 4mm long. I check with the designer and as expected, it's part of the design. Customer shows to everyone around her and they all agree it shouldn't be there. I explain my designer did it intentionally, offer a full replace or refund. I edit the line out and send example. She says she's not paying the return postage of just under £1. The emails go back and forth.
Funnily enough I noticed this line when printing but thought little of it, again, we've certainly sold 100's of this particular design in recent years and never had any complaints.
You can only do your best I guess but sometimes it just doesn't feel enough. Between this and the apparent constant flow of customers taking up more and more time just to go on and order a very small amount I just wonder if it's all worth it any more :-(
Rant over ;-)
