My neighborhood gym is a great place. It is family-owned, and I see many familiar faces while I'm there. Their signage could use some professional help, however. Words without images don't serve their entire clientele, IMHO.
Each locker room has 2 containers: 1 for trash and 1 for towels (notice both words begin with a "t"). They've tried various signs to note the difference, and have finally settled on these.
Even with the notation, I still see people picking towels out of the trash (or vice versa). It seems the problem could be easily solved by adding a trash icon or a simple image of a towel. No?
Another example: locker room signs. Evidently it takes more brain power to grok "Women's Locker Room" than a simple picture of a female. Who knew! I wonder how many people who weren't paying attention walked into the wrong room. I'm sure I never have (ahem). More and more I see the value of those little make/female icons on restrooms.
Maybe it's not that big a deal, for me. After 8 years, I'm learning the local gym customs. And, on a positive note, they always have pretty flower arrangements to brighten up the place.
