Really glad I haven’t encountered these so far, my local pump hasn’t dared adding these so far, despite their low prices. Benefits of living near the German border I guess, we can always take our money there. Currently the price difference comes down to spending time and 2 euros of gas to save 4 euros on a full tank, so not really worth the effort. But if push comes to shove I’ll happily trade some time in order to save a bit of money and not having to support this rancid business case.
