Following on. Getting to a car park and it costs 80p per hour. You have 80p in change but 20p is useless as it doesn't accept anything under a 5p coin.
Things that cost £X.99p. Just round it up to the nearest quid and be done with it. A wallet full of change is heavy. Especially when it never adds up to enough for a parking meter so you end up over paying because it doesn't give change.
