It's business with busy and slow days... maybe they were sharing the room to lower the costs because there was a convention in town and everything was very expensive, that seems smart to me. Don't we know guys who retired with absolutely no savings?
Guys who travel also have bad trips and others where they make a huge profit. It's a business, and many guys just can't do it for a few years.
If you think hiring a visiting guy will make you wonder how many guys he saw before and how many after you, don't hire him. If that will be always in your mind and you'll feel rushed or used, get a local.
If you want a clean bed, just host at your hotel/home.
The should have waited in the lobby and not that close to the door. Reminds me of Sean Xavier travelling with his ex and waiting in the corridor... C'mon let's don't be so obvious!
One more thing, busy days also happen to local guys.
