Who's a lefty?

We recently lent our angle grinder to a good friend, when he returned it he asked if Greg was a lefty as he'd turned round the handle in order to use it. Greg isn't a lefty and neither is Andrew which led to a discussion over who was using it correctly.

I sent him this photo today pointing out that they were all set up the way Greg had it - he proclaimed I was in a lefty shop :-) Xx
