Musings of an aging fan

I agree that the issue of employees for smoking-allowed pubs is a problem, and that I'm not sure there's an acceptable way to solve it. So to unpack a bit: assuming that there was an acceptable solution (robot bar-staff, perhaps ;) ) then I'd be happy with them; if the employee issue can't be solved acceptably, then I'd be worried for the same reasons you are. Partly, of course, the difficulty comes with drawing the line - after all, is it fair to insist that a fencing instructor must either enjoy fencing or put themselves at (admittedly much smaller) risk for someone else's habit? After all, people do get injured sometimes. (Granted it's much more unlikely that someone who doesn't enjoy fencing would want to become a fencing instructor than that someone who doesn't smoke would get a job in a bar, but the question is, in a sense, where between those two examples you draw the line....)
