This bears repeating. Commissioned sales associates often have to take time to attend training and meetings. As someone who has been in sales, no amount of training classes can compare to real world experience and that experience can't be gained by things like role playing. We are offering them a training experience worth the time it takes.
Our job is also to be sure we do not take up more time than is absolutely necessary to accomplish the task at hand. We are not on shops to tour a dozen new homes or have associates demonstrate every car on the lot. A good rule to remember is "pick and stick." In other words, if the car they have is blue you just love blue cars. If the only apartment available is a one bedroom, you will make it work. Love something and give them one or more opportunities to ask for the sale. If making an objection is part of your scenario choose something possible for them to overcome. Once you have given them their opportunities it doesn't matter if they take advantage or not, be prepared to make a graceful, and assertive if necessary, exit.
Equal rights for others does not mean fewer rights for you. It's not pie.
