I recommend adding a rob time so people who enter the bank after, during or before a robbery can know what stage is the robbery in.
So it would be: ROBBABLE, Robbery in progress, *Displays time till you can rob again*
Same idea for stores. There are times when you go in a store and you see that it was recently robbed, but you don't know how recently, so you have to wait sometimes seconds, sometimes multiple minutes.
It would be nice to have a timer displaying it.
