An unwillingness to learn

When even they don't know what they're talking about.

Read the instructions!!!

"I just started driving for UberXL."

"The amount of people who think they can fit 8 people with all their luggage into a midsize SUV is astonishing."

"I had one group sit there and stare me down like they didn't understand."

"I swear some people just have a mental limit for figuring things out and they all find each other and never get anywhere."- predict_irrational

One should always reserve judgment, as one never knows for sure what lurks beneath the surface.

Even if more often and not, you are left with little to nothing which encourages you to see what's there.
