I was in a hotel recently on one of my trips, and I saw this sign as I was getting off the elevator:
Ok... So I guess they are assuming that everyone will look at the sign and think that the Ice and Beverages are the same way as 402-430 (which was correct). When I saw this, I thought, "why didn't they just add one more arrow to make it clearer instead of having Ice and Beverages floating without any direction?" It would have been so simple, but for some reason, they thought that having people assume would be the better option.
I guess my point is that when thinking about how you're communicating something, think about ways to make it as clear as possible. The people on the receiving end (or who are getting out of the elevator looking for a cold beverage) will thank you!
