INTERN SHAMELESSLY INJECTED!

I've been doing an internship at a property company for a few days now. Today was the first time I was allowed to go with an estate agent and attend a viewing appointment. I learnt a lot, but I also noticed the way my "colleague" looked at me during the viewing. When the customers had left, I asked him about it and you can imagine what happened next! I didn't expect the end though... how am I supposed to go to the next appointment like that? I wonder what the customers would say?
