Thank you very much, David. I agree that it doesn't sound OK. How about this?

Bulgarians have a rather relaxed perception of time. They are never late for an exam, or an interview, no matter how heavy the traffic jams, because no one will excuse them for being late, or wait for them to come. For sure, those in charge of conducting the interview or the exam will not wait for them.
However, when attending business meetings, or going to dates, Bulgarians expect to be excused for being late. The following example is a good illustration of this Bulgarian phenomenon. Only half of the Bulgarians supposed to be present at a conference in Bulgaria have arrived. Twenty minutes later, the chairman announces that they have waited enough, excuses the people being late on account of the traffic jams and public transport, and opens the conference. Those being late continue to arrive, one by one, for as long as 40 minutes after the meeting has started.
