Kelly-Moore Paints at 616 South B Street, San Mateo, California.

I was in and out in 10 minutes with an exact color match and good/polite service.

The staff must hate working there because when I walked in, no one was around to help. I saw one employee in an office towards the back playing on his phone in landscape mode, so I assume he was doing something unrelated to work. He avoided eye contact at all cost. Another employee was on the phone for about 5 minutes as I stood next to the paint swatches, waiting to be helped. They finally were able to tell me the paint swatch I wanted was not available, but that they could charge me for a small can of it. No thanks. I'll get it elsewhere.
