In Glasgow it's usually things like 'what are you doing big man?' (Em, taking a picture?) 'Gonna take a photo of me?' (Naw) 'Is this gonna be in a newspaper' (aye, It's for an article on nosey b@st@rds)
If, in certain parts of Glasgow, people ask you 'was that expensive?' or 'Are you fae the social' then you are probably about to be parted from your kit, which may be then pawned if you are lucky, or wrapped around your head if you are not. Retreat to car.
I don't really do small talk, i'll suss within 2s whether somebody is into it, and may be rewarding to talk to, or whether they are just dull gearheads (present company excluded of course)
TBH i'm more interested in what kind of photography somebody does, who their influences are, if they talk a good game I may exchange flickr names. Unfortunately, despite being blessed with a massively diverse range of scenery, and despite great gear being relatively attainable many serious hobbyists in Scotland spend their time trying to recreate last years Joe Cornish or Colin Prior calender (both excellent FYI) I don't think there are any more interesting images to be taken of Eilean Donan, Black Rock, or the old man of storr, it's like bingo or trainspotting.
