Has anyone used a "standard" for tipping the bar staff that makes drinks for those who use the Diamond/Diamond+ lounges. The same with the person working as the Conscierge in the Diamond lounges. Even if he or she has made a couple of drinks and been helpful in providing information and answering questions.
We tipped what we thought was a good tip to the bar tenders working the lounge as well as the Conscierge occasionally making the free drinks for us but would like to hear from other Diamond/ Diamond + members who has experienced this and what they have tipped the bar tenders and Conscierge. This is not about their service being good or not so good but as a token to show our generosity and gratefulness.
Thanks in advance !
