English, two-stage translation. There may be questions.

The approximate translation of 1 is that the people in the shop let him try on many pairs of glasses, but Barry always said, "No, I can't read …" The man became more and more confused, and finally he said, "Sorry, can't you read at all?" "Of course!" Barry said angrily, "If I can read, why should I buy glasses from you?"

My understanding is that Barry is illiterate = = Seeing that everyone else has to wear glasses, he feels that he can only read with glasses (old man ...) ... so there is this farce = =

A long time ago, British judges often judged whether a person was lying by giving him some dry bread. If the man can't swallow dry bread, it means that he is lying. Although it seems strange and stupid, they think it is a good way to know the truth. It is difficult for a person who is worried about something to swallow dry food because he has lost his appetite. ) Maybe there is something wrong with my translation. Please forgive me. )
