I've been doing similar type locations instead of the AMP's that have the standard HF + tip. These locations are POP and usually have time options, SS, Hhr, or Hr. They also get right to the point. I've had a couple of good experiences and one pretty bad. The bad being no personality and disguised rush job with many promised amenities left out. All girls were 25-30. My trick now is I tell them i'm only offering to give short stay because I am always rushed and if i'm not rushed I will add at the end.
