The parking garage at my HMO building has 7 'levels'... 2 below the entry or 'ground' level, and 4 above. There is a elevator/lift and also a set of stairs for those who choose exercise. It can be confusing when you park partway up the curved ramp between stairway/elevator entrances, so inside each door to the stairs, there is a sign reminding you,,"Remember you are parked on Level 2." or 3.. or lower level 1... whatever.
   This very nice... but if you walk down from, say, level 2 or 3 to the door that leads out to the path to the main building, there is a sign saying "Remember, you are parked on Level Ground."... which sounds a bit odd to begin with, but also is totally useless, as you did NOT park on the ground level. If you see the sign at all, it means you arrived there FROM some other level or are entering the stairs to walk TO some other level.
   Once you ignore this and walk up or down, the nice signs will tell you when you have arrived at the relevant door.

This is the sort of detail I notice. There is no use bring it to the attention of the management, as they would just say... "Oh, you know what it means!" and yes, I do.... but had I been in charge of signs, that one would merely say "Ground Level" to tell walkers they are where they need to be.
Oh well....
