Shangri-La properties in Colombo

The hotel is a bit old, and the facilities in the rooms are showing their age. We arrived around 8 PM on the first day, and there was only one person at the front desk. This staff member was incredibly unfriendly. We had booked three rooms, all for two adults and one child, and asked for two key cards for each. She actually lied, saying there was another card already in the room. Secondly, when checking in, we offered our credit card for a pre-authorization, but she said it wasn't needed. This meant that all subsequent room service had to be paid in cash, which was extremely inconvenient. I suspect this front desk staff member on the night shift either has psychological issues or was intentionally messing with Chinese guests. Shangri-La was founded by Chinese people, so why was this happening? The next day, we cautiously asked the front desk for a second key card, and it was given to us easily. The service quality is inconsistent, with some good and some bad experiences, but most of the staff are friendly.
