The reason you couldn't get a taxi is that you were standing on a road with a double yellow line. A double yellow line is illegal for cars/taxis to stop for any reason. Buses and minibuses can stop as long as it's at the designated bus stop signs/areas.
1 hkd for an egg tart. I call bullshit as I went there yesterday, and egg tarts are 10hkd. So you actually spent more than 100hkd. I thought it was too good to be true . Nice try for deceiving us 😂
The video is very misleading. $100 is in USD. There are better way to spend the $100USD than wasting your time in HK. Also it's obviously paid by the Chinese /HK government to make this video to mislead foreigners thinking HK is wonderful, nothing wrong here, business as usual, etc all BS.
