Cheers, Pauly.
Blimey......they're not hanging about......when I got home last night the letter for the assessment appointment had already landed! Appointment for Tuesday 14th. So I'm going to have to see if I can get an appointment with that optician next week. Tuesday's taken care of by car repair bookings, though. And people on holiday and days off will make it awkward to squeeze a bit of time off from work, but they can sod off. Need to get this looked at and my eyes are more important than whether they're undermanned for a few hours!
