It’s amazing how clueless some people are. They bring in a picture of something and expect you to know what size it is. Guy shows me his pipe going into his sprinkler system. I don’t work plumbing and wouldn’t be able to guess so I ask did he measure it. Nope. Someone shows me their tile and wants a close match. The picture is dim and the color on his phone is lousy. Nope. Not going to try.
