What happens in this scenario? N=1 anecdote from a traditionally managed Japanese company. If you (a twenty-something Japanese man) happen to say お先に失礼します。(announcing you're leaving) at 6:00 PM in front of the company's CEO during a site visit, and the CEO says, in a shocked voice, "I suppose you have somewhere more important to be right now.", and you say "Yes, I'm going on a date.", you can look forward to six months of nuclear-tipped ostracism from your colleagues and, when you complain to management about it, they will tell you "[Foreign employee] is more Japanese than you are; ask him."
