It depends on who I'm seeing. If she's not a well known provider, and is in a dive in a not so good part of town, my spidey senses are going insane. Granted, it's the typical scenario for some providers who are working their way up, but still scary. Seems like the BF/pimp/abettor is just lurking in the shadows.
Going through a fancy hotel lobby isn't always fun, either. The emptier the lobby is, the worse the feeling is when you can't immediately locate the elevator. Even if I'm initially wrong on my guess as to where the elevator is, I just keep going in that direction and take the stairs. I don't want the desk clerk getting too many looks at me, because combining it with any confusion on my part makes me an easily idenfiable suspect to call the cops on (yes, it's easy to call security on a 200lb black man who's looking confused in a lobby
).
Ladies, if my heart is pounding when you greet me with a hug at the door, the above scenario is probably why (that and I'm always a little nervous prior to a session, anyway).
