Hello Malcolm, At the moment I can only think about one time, and I found it very embarrassing, but am sure that I will think of some more. Anyway seven years ago when we moved from Heathrow to Dorset, we needed a new built in oven for the kitchen, at the time, I used a very strong magnifier to see to put my oven on the correct temperature, well we went to Comet and Currys but all their built in ovens were up high, and ofcourse I could not possibly have known if I could use them, so in each shop I had to ask for a step ladder, to enable me to climb ip to find the oven I could use. I am sure everyone was thinking what is that stupid woman doing., so I rushed as I felt a complete idiot, that oven has been a problem since buying it. The element went last Wednesday, forthe third time, and they are not repairing it until tomorrow, so have not had a decent meal all over Easter. Best Wishes Elaine
