Believe it or not, there are plenty of jerks who like to make appointments, find out where she is staying, and then never show up.

The two call system helps her avoid these guys.

why the 2 call system for providers??? I call get directions to place X, the 2nd call get me the address; why not save a call and give the address?
If 2 call is good should I use when a provider come to me

This has been asked before. The link is a providers response.  Learn to use the search engine, mrfisher needs a break every once in awhile.

If just a phone call was all it took to find out where she's staying, she could wind up with unwanted visitors.

I might add that in some cases she may have someone there prior to you or after you meaning she may not want you showing up early before she is ready for you .Many guys are very time considerate some like to show up early or late and think that will be fine .Maybe even they are anxious to get started and she is not wanting you there early before she can get ready , possibly say goodbye to someone else and they DO NOt as i am sure neither do you want to pass someone in her hallway .She would want to shower get ready and not have someone there 15 minutes early when her hair is still wet and she is wearing nothing more than a towel.Getting the girl nervous and rushed or even possibly feeling pressured , making her feel you come along and want to change the rules as this is standard procedure in all states is not going to make for a great session .When in Rome......
