What happened to me today doesn't happen often, but I've never found a good way to deal with it.
The backstory is that I am dyslexic and fully literate, but I do struggle to fill in forms because I don't find it easy to write block caps or to copy information. I can't do numbers at all - any number longer than 3 digits I can't memorize without a huge struggle, and if I copy a number I will almost always reverse some digits. I cope fine in my day-to-day life (which is postgrad study), but I struggle with admin tasks, esp. banking. I'm aware that people often assume I'm illiterate and trying to hide it.
I'm trying to keep this short, but basically the bank cashier today asked me to come back with 'someone who looks after you'. I'd failed to fill in the numbers on a form correctly, twice in a row, after telling her I struggled to do this and would she mind helping me. I assume she thought I was of very low intelligence but I felt really humiliated (aside from the fact I don't can't imagine how horrible that would feel for someone of genuinely low intelligence who was trying to manage on their own).
WWYD? I did speak to the manager as I wasted a lot of time filling in forms incorrectly and not being given any help from the cashier, but I am considering putting in a formal complaint.
