I thought about that but I didnt see any rolls last time I was there? Will check again tomorrow maybe I just missed them
I think rolls are usually on the end of the buffet nearest the rest of the lounge, other end from the cutlery and the lard hot items. There's also toast on the buffet, which arrives toasted and over time advances to dessicated, so if you get a fresh batch it's OK for a toasted bacon sandwich.
Also I suspect the staff might bring you a roll or two if you ask.
