Some of the younger bar staff hereabouts have taken to calling me 'buddy'. 'Alright, buddy?' 'What can I get you buddy?' No! No, no, no! I am not your buddy. I am not, for that matter, anyone's 'buddy'. Please, desist. Do not address me thus.
To be fair, I find 'mate' almost as annoying, and I also dislike 'sir'. In fact I can't think of any term they could use that wouldn't annoy me at least a bit. Totally unreasonable. But 'buddy' is the worst. 'Buddy' really gets on my tit. I don't know why, but there it is.
(Funnily enough, if an Aussie calls me 'mate', it doesn't bother me at all. No idea why. I guess I'm just too old for logic...)
