Aspie-ish, or minor OCD?

[jesusrock7]

Lately I've noticed that whenever I adjust the tv volume at home I increase/decrease it to the nearest 5 or 0 (45, 70, etc). Then at work if someone is dropping off film to be developed at my photo lab, I almost always put the pick-up time as #:00, #:15, #:30, or #:45.

Is this an Aspie thing?
