I work at a home improvement store in the paint department.
Occasionally we will have paint marked down to $9.00 a gallon. It's sold as is. We aren't allowed to change the color at all. Most of the time it's color matches that didn't turn out right or if the tinter messes up. In this case it was a return.
With most returns we change the color slightly so the original person can come back and get their pair t for cheaper. In this case we couldn't because over a quart of the paint was missing. (you have to keep a certain colorant to paint ratio to make sure the paint dries)
Lady: Excuse me can u make this paint more blue?
Me: No ma'am our markdown paint is sold as is and I would not be able to add any color into that gallon anyway because a quart is missing.
L: Do you have any blue mark down paint that I could add to it?
M: I can check the desk to see if there is any that we haven't priced yet but you would have to buy both cans.
As luck would have it we had a quart of a dark blue that just needed to be marked. It would have only been $5.
L: That's not blue. I work with colors and I know what blue is. What if I get u to mix me a new quart to add to the gallon?
Now I'm not messing up a quart of paint if this lady doesn't like how the gallon turns out
M: No ma'am. I'm not able to do that because the paint is sold as is. If u would like to buy both a new quart and the gallon you can take them home and mix them together. I'll even give u extra stir sticks.
Well this didn't make her happy and she walked to the customer service desk. She complains to a manager and she wins. The color she picks out for her quart? Green. She's been asking for blue but picks out a green?
So I mix the paint together for her and it's nowhere near what color she wanted. Then she pitches a fit when she finds out she has to pay for the quart of paint that I put in the gallon!
She paid $20 for less than a gallon of paint when $25 would have gotten her a full gallon in whatever shade of blue (green?) she wanted
