A written chat is not a good channel of communication for no verbal language, hence, is quite easy to make mistakes because each side might add different context to the sentences. This might cause difficulties whenever a correction, a negative or a disagreement has to be said in a written chat.
As an example. Just now I was having a chat with a client. We're both located in a latin country. We know each other for a couple of years and we meet in person several times during the year. Neither of us are native english speakers, but often conversations might include english words or expressions whenever spanish does not have a known translation.
During our last conversation, he was busy with a class and tried to write (in spanish) "we have a coffee break in five minutes", where coffee break was written in english. But unfortunately he wrote instead "we have a coffee brake in five minutes", using the word brake.
I'm not sure if he just made a mistake and he actually knows the correct word, or maybe he has been using the wrong word for a long time. I'd like to spare him future jokes from others, while not being myself pedant about his mistake.
