This one drives me insane every morning.
Close to where I work is a Chinese Super Market, proper weird and it stinks of dried fish.
Every morning on my way to work there is anywhere between 2-15 Chinese pensioners that take the bus in the morning to go to this supermarket. Now, while it can be annoying listening to up to 15 pensioners loudly conversing in whichever Chinese dialect it is first thing in the morning that isn't what makes me fume. What makes me fume is when we get off of the bus instead of walking to the cross walk the pensioners will hold up four lanes of traffic as they cross the road IN FRONT of the bus that just dropped them off preventing it from continuing on its route.
One of these days a car isn't going to see them walking out from in front of the bus and there is going to be an accident. I won't have a lick of sympathy, the cross walk is a 2 minute detour for them to cross the road safely.
