Clock watcher and time cutter, they count the time from your arrival at the door, at best from the time you go into the room. The first 5 minutes are already wasted on paperwork and with bringing away the money to her pimp , followed by tabbing around for the condom.
I remember times when a massage was offered, or a cola, juice, water, no one kicked you out after exactly 15-30-60 minutes, especially not as a regular. Today you are not valued .. just quick money with the lowest performance. And yes there are exceptions, but they are becoming increasingly rare.
