We were out cycling today, and I was desperate for a cup of tea. The tea was fine (except that it came as a pot of boiling water with a tea bag in each cup, which seemed a little odd).
We paid without thinking about it much, but , afterwards, I thought 'that much, for 2 tea bags and a bit of milk?'
Anyway, I know it's a 1st world issue, but what would you expect to pay?
