Intern shamelessly splashed!

I've been doing an internship at a real estate company for a few days now. Today I was allowed to go to a broker for the first time and be there for a viewing appointment. I was able to see a lot, but I also noticed the looks from my "colleague" during the tour. When the customers were gone, I asked him about it and you can imagine what happened next !! But then I didn't expect the end ... how am I supposed to go to the next appointment? What would the customers say ???
