Beating People on the commute who have a better bike

I don't get the animosity over drafting... You sit behind me, I sit behind you, we get there faster and can tell from each other's ride/clothing/pace that we both ride regularly (aka not just commuting).

It's more the people that don't fit that bill that are annoying... the ones puffing and panting as they stick to your wheel, happy for the free ride though.
