Usage examples of "cheap and cheerful".
I used to be puzzled by the curious British attitude to pleasure, and that tireless, dogged optimism of theirs that allowed them to attach an upbeat turn of phrase to the direst inadequacies - 'well, it makes a change', 'mustn't grumble', 'you could do worse', 'it's not much, but it's cheap and cheerful', 'it was quite nice really' -but gradually I came round to their way of thinking and my life has never been happier.
