I have a gym nearby that’s very expensive and focused on lifting. I am always so impressed by how the weights are always where they should be. The culture is amazing. In addition to people having respect for this, the weights there are colored which helps spot it visually. So the 45lb is blue, 55lb is orange, 35lb is yellow, 25lb is green. In my very anecdotal opinion this and well labeled racks go a long way here.
Compare another gym I use when I’m working from home: weights everywhere, no weight where it should be, and the weights themselves are inconsistently sized even at the same weight. It frustrates me to no end to have to pick through weights to find the ones I need for a lift.
