or how much time they spend going to get it. or even how much it might improve your mental arithmetic skills.

as I spent so fucking long this morning trudging to the shop because I was 5 p short of my fare.

I'm one of those people who, if the total for something is $4.36 and I'm paying in cash, will dig around in the wallet to find the .36 so that I can either pay exact, or get an even numbers of dollars back.

I had 1.55 and a fiver.

ffs

I'm quite happy to pay exact. but the buses where there is literally no change are starting to do my nut in.

I will also do calculations and use pennies to get back useful coins, like quarters.

I've paid 2 quid for a 1.60 fare because I haven't got the right change and it's too much of a pain to go to the shop.

also, nowhere sells anything for 40p any more.
