I'm beginning to recognise the various customer types that Peter services. There are the terribly poor ones who can hardly afford Peter's rather expensive rates. They tend to be in the council flats and only call Peter when it becomes obvious that the  council are not going to turn up and make the repair for them. And when the situation is almost out of hand. Then there are the estate management  people, including, sometimes, the council themselves, who are looking after a building. They are usually spending someone else's money, so they don't care and they'll call out Peter for a trivial job and pay the full callout fee and exorbitant hourly rate without a blink. Finally there are the well-off people in these Docklands developments, with fancy interior decor and what Peter calls 'slick' plumbing.
