So are people in Islington more gullible then the Welsh and getting ripped off?
I suppose you could put it that way - or, at least, say that people in Islington do not adequately think through the situation as regards the services of people like electricians.
People in Islington are used to, and accept, paying appreciably more for many things than they would have to pay if they were in Wales. In many cases, the increased cost is justifiable on the basis of the much higher overheads involved in providing the services (or even goods) in Islington - particularly if the provision of services/goods involves the acquisition or renting, and running costs (rates etc.) of, 'premises' - hence, understandably, much higher prices in pubs, restaurants, hotels, private hospitals etc., and even services provided by (premises-based) hair dressers, solicitors, architects etc. etc.
However, in the case of tradespeople like electricians, who don't need 'premises' and work entirely 'on-site', there would seem to be very few overheads which will be greater in Islington than in Wales - maybe a bit more travelling time and parking etc. costs (but even that probably offset by less mileage) and somewhat higher vehicle maintenance costs, but I can't think of much more - can you? Hence, if I'm right, then if they thought things through, I'm not sure that the people in Islington would see the justification of (hence be able to 'accept') paying an electrician a lot more for doing work in Islington as they would have to pay for the same work in Wales.
However, there is a more general issue (essentially a partial vicious circle) which might possibly be some of the reason for their acceptance of the higher cost of services in Islington .... since, as above, many things in Islington
are (for justifiable reasons) more expensive than they would be in Wales, there is probably an expectation (and 'acceptance') of the fact that incomes need to be higher in Islington in order to achieve the same 'standard of living' - i.e. that every tradesman needs to 'make more profit' in Islington than he/she would have to make in Wales.
However, I suspect that isn't the main basis of the thinking of people in Islington and that your suggestion of 'gullible' is probably closer to the truth - i.e. because they know (and accept) that (for justifiable reasons) they have to pay more in Islington for their pint of beer in a pub, restaurant meal or consultation with a solicitor etc. etc., they also 'assume' (always dangerous
), without much thinking, that the same is justifiable for the services of an electrician etc.
