Spot On
Personally, I find the sign with the turtle illustration and coloring inside the lines example more persuading, but this is the same kind of passive-aggressive behavior people often use when commenting about someone who won’t take the time to park properly (to put it nicely).
People can get very creative when it comes to passive-aggressive messages, bot you must admit this is one of the most creative passive-aggressive signs anyone has ever made. With so many words, it definitely gets the message across – don’t park selfishly, don’t take up more than one spot, get your own spot.
