I’ve been paid for some work I carried out in ETH. Is it standard procedure for the payee to bear the transaction fees?

So yeah quick question. Probably rather obvious that if you agree to pay somebody X you pay them X.

However Im pretty new to ethereum. I am kind of working for somebody and they agreed to pay me 0.04 ETH for the task.

I got paid, but it seems like they paid me 0.04 minus the fees, so I ended up with slightly less, rather than 0.04 plus transaction fee.

Being rather new Im not sure if this is the norm, like if you pay somebody is it expected that you also pay the transaction fee? I know its a rather dumb question but I want to be sure I am not violating the norm or some unspoken rule before I tell the person they were short. We didnt agree anything in advance, just told the amount I would be paid.
