German Guys,
Not having a mini bar stocked with complimentary beverages is not new with Celebrity for Sky and Celebrity Suites. I recall be surprised with this policy pre pandemic when we were in a Celebrity Suite. What I have observed is some butlers will quietly bring what you request. Yes, you bring back soda, beer etc from the Retreat Lounge without question. Based on all the chatter here, I bet the Butlers are being closely monitored.
