Rant: Client ruined my Christmas

for a project they won't do anything on for 2 months.

I've been working with this client that runs his father's manufacturing company. He treats us the same way he treats his peons.

• We often meet him at his home (1.5 hours away from office in traffic) where he makes us wait for an hour EVERY DAMN TIME. His peons don't even offer us water and disappear.
• Keeps talking to me in Gujarati when he knows I don't understand it and scolds me for not catching what he says.
• Regularly address me by the wrong gender in Gujju (Calls me a man, weird)
• I have been working with them and often the stuff our teams are working in so misguided that it does not see the light for weeks and months.

So anyways I am going to have to work through Christmas on a project that I'm sure is not going to be of use for the next 2 months. My senior tried to ask him if he is sure this is immediately required but ofc he wants work done in the next 5-7 days
