I don't know! I very rarely have drams out around here--only get out once every two or three weeks, and then just for pints with Bobby. (It's usually bowling night...but that's another whole story.) But I'm on the road a lot, and frequently find myself in walking distance of a good pub like Thomas Dunn in Québec, or L'Île Noir in Montréal; or in some hotel bar with good old 'Fiddich and 'Livet. Have enjoyed quite a bit of Glenlivet lately. Anyway, it's ahrd to quantify. But at that, I'd say very likely it's well under 25%.
Oh, I'm discounting that month in Scotland...okay, 50%.
