When I get to work I dismount my bike to the left as the door opens from the right. When I get home I dismount to the right as the back gate opens from the left. At lights I don't think about it and unclip whichever foot is at the top of the stroke. If you have ever had a dirtbike with a 38" seat height you quickly get used to dismounting on whichever side has higher ground (you also get used to low speed tip-overs).
