I went to a tool shop around these parts (not Bunnings), and asked the counter jumper where their fractional metric drill bits were.... the blank look suggested I explain further - you know, drill bits like 3.2/3.3/3.4mm etc, sorry, drill bits only come in half mm increments.... he didn't believe me when I said I actually do own several of such bits.... after thinking I could of got that pearl of advice from Bunnings, I went elsewhere....
Don't get me started about AppleStore 'geniuses'.....
