Allan is generally uptight and deadpan, often playing the straight man amidst the antics of others. He is a bit of a neat freak, as seen in "Desmond's Big Day Out," where he obsessively searches for a missing paperclip. Allan's love for cheese is evident in the same episode, and Mr. Boss acknowledges this craving in "Frowning Friends," suggesting he search for some. Allan also tends to get impatient quickly, as demonstrated when he becomes aggravated while waiting for assistance and escalates.
