festering looseness

I keep seeing loose signage, and I can't stand it anymore.

Here are a few instances from my daily sphere of operation:

• A note on the bus about operation on "Martin Luther King Day Jr." I was wondering if that was a subsidiary or a competitor to the 7DayJr. (convenience store)
  
• Another note on the bus about not bringing your "bike-cycle"
  
• This to me seems like a modern marvel. A bicycle with cycling bicycles... perhaps?
• A note on a door in a building :
  

"Don't use this door anymore

Until Further Notice "

• untight

• "Machine is Broke"
  
• wow.
  

Crank it, sign poster.
