“Theatre in the UK has never been cheaper, we’re told. The internet’s overridden with offers, deals on West End shows put Broadway prices to shame and the National’s £10 Travelex season has convinced many that a night at the theatre doesn’t have to be horrifically expensive. That’s all very well – I love a bargain – but maybe thrifty theatre-going comes with a hidden cost. You might save a few quid, but does it leave you with a miserable experience?”
