I (a Scot) draw a 1 with a serif and a 7 with a bar (and a Z with a bar)
because it was necessary for university maths not to mix up |, 1, 7, 2 and
Z, and the habit has just stuck.  Mathematicians, of course, have lots of 
other ways to decorate their fonts.

And I write zero with a slash and O without when clarity requires it (e.g. 
copying down serial numbers) and sometimes at other "computing" times too, 
though not consistently, because it helped the card-punch-operator.

I did have a summer job as a student at a place which did the 0 and O 
the other way round, which caused a bit of confusion at first.  I don't 
know why, because it wasn't the kind of place which would have been 
contrary about something like that.  Given that I got the job because the 
person I was working for didn't understand IMPLICIT INTEGER and couldn't 
see why his FORTRAN wasn't giving him the results he expected, my guess is 
that it was just a case of someone hearing about a good idea and just 
implementing it in their own way.
