Since a necro tered, tell u a story

A university of mine got grad who accepted to do intern at Company Z
She put a lecturer as reference which the lecturer agreed to do so

Dunno wat happened, the grad didn't show up at the Company X on first day despite signed contract

Lastly, cases brought to court
The lecturer need to be summoned to the court

From that time, the lecturer never become reference for students again

That Company X put all effort money to sue the intern
