Aside from the obvious things (unfair CBSA regulations, people showing up late, people not reading the rules/FAQs, etc.)
what really annoys me is
Goggle Fog.
Sure there are anti-fog cloths, turbo-fan goggles, etc. but sometimes goggle fog just happens anyway. It always seems to happen to me at the worst moments too.
Then again, maybe I need some better goggles.
