I went to one of those shops that were advertised at 120. And yes they will ask for 160. I did mention it was posted at 120. Then it went to 140, 160 to 180 as type of services were outlined. When you are in the room end up haggling it is unpleasant. Either you choose to stay or to scram without embarrassing both sides the end result is unsavory. It is one of those experiences you have to learn and earn yourself. Was 120 a shill? If goal is to get you in the room and end up being there regardless of outcome then you will know the answer.
