At last! A truly meaningful poll on a subject of earth-shaking significance! Let Diageo, Pernod-Ricard, and all the others ignore this at their peril.
I'm with the majority (so far)--remove the top, leave the rest. Use a knife on wax (a'bunadh). The foil tops have been accumulating in a pile behind my keyboard
--just pulled the drawer out and found exactly forty of them. There is a logical explanation for this, though: I have no wife. (And Mr Picky won't even come in here--he yells all his comments from a small room in the back of my mind.)
Even my bachelorly slovenliness has its limits. The seven perforated foil strips I also found back there have just gone in the trash! That's enough housecleaning for this week.
(Next week I will no doubt see perforated foil strips from whisky bottles going for big bucks on EBay.)
