It's another example of how expensive it is to be poor.

I was thinking about starting a thread along these lines. I may still do so sometime, if you don't mind.
I've seen signs in petrol stations where they tell you they'll add £10 admin fee if you can't pay then and there and have to come back in the next day or two. This represents approx an extra 10-15% on a full tank, but when you can only manage to put £10-£20 in at a time anyway, it's a lot extra (yes, I realise they're a business not a charity and fully within their rights to do so, you've taken fuel for which you had no means to pay, etc. etc.).
It's like when you sail close to your maximum available funds with your bank and dip into OD (or over your authorised OD) and get fees whacked on. Yes, it's all in their T&Cs, you've temporarily used their funds without asking them, I get that. All it means is that people with very little money available at the end of the month (for any of a myriad of reasons) then start the very beginning of the next month with even less.
It massively annoys me when you see the periodical government reports berating fuel stations for ripping off motorists, saying that, with current fuel markets, they should be charging a penny or two less per litre. That's as maybe, but when they're taking something like 85% of the cost to the motorist in tax and VAT (I thought it used to be illegal to add tax and then charge VAT on the whole amount - may be wrong there), it's extremely hypocritical of them to hurl mud at the retailers.
Also, I just had to tax the car and saw the several options open to you. The standard quoted price is if you can afford to pay the whole 12 months upfront. If you can't afford it and have to pay for 6 months at a time (whether or not by direct debit) or monthly, they whack an extra 5% or so on to the total cost. I understand when private companies do this, as they can't get interest on your money if you don't pay it upfront, but for the government to do it (and it's all automated, so it doesn't cost them extra in admin costs) is an absolute slap in the face.
There'll be somebody along soon to say that running a car is a privilege and, if you can't afford to cover all costs upfront, you should just use the non-existent bus service to get to and from your 12-hour night-shift. Alternatively, an electric car will save you hundreds in tax and potentially more hundreds in fuel, so why not 'simply' shell out thousands upfront and buy one of those instead.
