Lano Hotel (Lhasa Potala Palace)

I have to give 1 star service for this hotel. This hotel should put having a local phone number is a requirement for check-in. They don't have experienced of handling non local guests. Front desk staff said they can't let me stay, because I doynt have a local phone number. They will assist me to cancel and refund. She said it so lightly, doesn't really care if I had long day, if I'll be able to find other place to stay. However, when I show her my booking from trip.com (in English), asking how can I cancel this? It's after 6pm. She said she doesn't know how to read English. I told her that the other place allow me to leave HK number as my contact number, and I can receive phone call, why can't I do that here? She was about to call my HK number, but then she can't find + dial? Then she said she doesn't know how to call non local number. She said maybe need to register for international call? Strange, cause Didi driver call me on my HK number all the time. It was late, no point argue-ing and I don't feel like searching for another hotel, I don't have any options. I gave a local number, told her it's a friend's number; and she let us stay.
