I find that this useless stress thing goes in most parts of daily life here in Hong Kong. With the irony that the more people seem to stress, the slower things seem to happen...
Just the other day I was buying some stuff at a store and had picked one thing out, the shop-owner immediately took the thing right from my hand and blurts out; twentyfourdollarsthankyoubyebye, without a thought about the fact that I might actually be interested in buying something else, which I in fact was going to, but didn't bother after the great service I received.
Even more unbelievable there was no one else in the shop, so no one was waiting for her service, good work!
