Standing in for Realtors?

[Tyra General]

Hi,

I was told by a Real Estate investor who I can no longer get in touch with, that there is someone that gets paid to sit in the house that a realtor is selling until the realtor arrives? I'm guessing they were there to show the house to prospective buyers when the realtor could not make it? Is anyone familiar with what they may have been referrring to?

Thanks & God Bless,
