Idiots who order 50 things throught a drivethrough because they're too lasy to park their car and walk their fat asses to the counter to pay for something and instead they hold up an entire drive through.
People who take forever at the bank machine because they choose to pay all their bills there instead of at the teller like normal people with brains and instead hold me up and all I want to do is withdraw money = 30 second task.
