I visited the #25 lounge yesterday.
Two lounge dragons at the desk talking. A third standing at the self-service check in machines, but after realizing I was flying AZ directed me to the ones behind the desk.
Took them 10 seconds to notice me standing in front of them to have my BP scanned. Not a single comment or welcome, grabbed the BP, scanned and gave it back. Meanwhile she continued talking to her colleague. I then entered the lounge as it seemed that I was given entry.
Often the term lounge dragon is not warranted, except for AMS I am sorry to say. Both lounge #25 and #52 has some seriously not-service minded people employed. That is at the front desk, but also (for example) the ones bringing the food out - more than once I have been quite annoyed with them yelling instructions to each other, in an otherwise very quiet lounge.
