"Self check-in"

I bring my father to the Garrett Anderson eye clinic on a regular basis and we are very happy with the care he receives. The issue I have is with the self check in which involves ringing an extension number to announce the patients arrival.

The keys on the phone are very small and difficult to read. When I was in the waiting room this morning 5 patients arrived and none of them were able to check in without assistance.

Surely in the eye clinic it would be a good idea to have a phone with large, clear keys!
