I find its the big posh houses with there garage full of expensive cars that are the worst kind of people to get paid from....im sure they look at us like scum... that we should be grateful for the work.
Honest hard working folk that have saved for years to have work done are trying to pay before you finish. ....which makes it even worse when they get screwed by the cowboys out there
Its funny you say about the more upmarket customers - apart from commercial companies (don't pay agreed amount, 3 month payment delays, can't find you on CIS excuses), the only customers I ever chase for payments, are those who should have been able to pay it with change from their pocket. And its always the excuses like "the grouting is not quite right" or "the tiles are not straight." Meanwhile, my council house tenant customers have the cheque ready or the money transferred before I get home from the job. Most of them watch me tiling (makes a change from watching dvd's), always make me tea, and always tell me what a great job I did.
Quality.
