In the C10 UC right.now. Had some issues getting in as my boarding pass didn't scan, although it came out of a UA check-in gizmo earlier today. They reprinted it and it worked.
Asked whether i can have more drink vouchers later and was told no. I guess it's since I'm flying with LH and since it's an award ticket, although booked on united.com. Some are more equal than others...

I wonder whether you can rinse, dry, and repeat by going to another UC. Will you get another bag?

BTW, the food options are abysmal. The saving grace is the 'free' Boston Lager and prosecco (although I think the brand was downgraded from Mionetto since my last visit).
