First independent day at Bondi Junction

This is the first independent day at Bondi Junction. Before that several persons mentioned that the clients in Bondi Junction were hardest to deal with. Today I were careful, clients were ok, they were not too hard and they came from higher income community.

We have no receptionist now. Amy went to Wollongong. Allison come today. Van back from his holiday.

I need business card for the Bondi Junction. Contact with Ginny with my key in Hurstville. So far so good.

Overall still happy for this new job.
