  Well seems my 100 minute appointment was actually two 10 minute ones separated by 80 minutes which left me stranded in town with nothing to do - fortunately I sought refuge in the library where a copy of The Times entertained me, as did the rather comically written sign saying 'Watch out! Thief About! ' further reading informed me that some lost soul is going around there stealing... not really a criminal mastermind who ever they are. The actual optician was a finer guy as any - had a wonderfully dark sense of humour which I admire in anyone, especially in people such as him. 'We'll give you a free trial, come in after a month and we'll sort out payment, assuming you’ll make it back!’ Sadly I couldn't begin decorating today... hopefully tomorrow...
