At work, customers regularly get a bit corss when asked to fill forms out, because they haven't got their glasses.
If I take my glasses off, I can't see either! That is why I wear them!
A man came in yesterday to discuss a complicated query and get information. He then informed me that he couldn't hear what I was saying, because he was not wearing his hearing aid.
Why set out from your house to have a conversation with someone to get information from them, and not wear your hearing aid?
AIBU in failing entirely to have any sympathy for the people that for whatever reason (in most cases IMO vanity) don't wear the devices that they are provideds with to ensure that they can go about their business unaided?
