Client: Are we getting the finished site next Monday?

Supervisor: no it should be the week after, that's the date I have on our dev schedule.

1st week into the project, we pointed out the PM messed up the project end date (he took beginning of the final week instead of the end of week) and apparently he(& CEO) didn't bother to inform the client about the mistake.

WTF PM you f-ed up every single project since joining the company
