giving my phone number to papa johns is in no way like Facebook. I have given it to them for business purposes. Being a business they have to abide by certain laws. If i tell them to take me off their list, and they do not comply. I have grounds to pursue other legal avenue's to solve the issue.
Now if I throw my phone number up on the Internet for all to see, I have not entered into any agreement with a single person, its more of a group, as I have picked what friends have access to my phone number. I haven't given it to them for the specific reason of providing me with a service such as Pizza delivery. I've provided it as a way to communicate with me whenever they feel like it. I don't expect nor have I had papa Johns call me up to see what I'm doing on Friday night, or if I can come over and fix their computers.
Add to the fact that if I do not have your number in my phone it does not ring, you go strait to voice mail. I do have a limited amount of annoyances on my phone. After working in a service industry you learn to protect your privacy so you do not have people calling you for personal tech support at 1am right when the 4th set starts and something breaks.
My address I could care less about, I have a door, It has a deadbolt. I have shades that close and a doorbell I can disconnect. If I ask you to leave and you do not, I will call the police to talk to you about the finer points of trespassing. If you head out onto the sidewalk/street go for it. I don't care.
Unlike you, I find it easier that less people know my number, as its usually for some annoyance that is of a business sense during non-business hours. I do not do that, and will not ever do that in the near future. My nights are my nights. call me during the day. I will honestly tell someone that if they call me after 6pm, then proceed to end the call. (I'm lucky enough to be able to pick and choose my business contracts I decide to pursue) If someone needs to get a hold of me and doesn't have my number, I do understand they could get it from a friend that has it. (Although most of my friends know better). But once again, it goes back to the voice mail. I am much more likely to answer your request via e-mail, as that gets pushed to my phone at all times, at any of my 4 accounts i generally use. And I am able to deal with it quicker and at my convenience, which isn't that what communication has come about to?
I do understand my predicament is slightly different than yours. As soon as I feel the need to fully invest in my side business I'll add a line onto my cell phone contract and have a separate line, which would alleviate most issues, besides the people that wouldn't get that if that phone is busy my personal phone is not a substitute for the work line. But they would hopefully be able to figure it out after a few calls not returned until the next business day.
So I guess its not so much privacy that the issue is, its more the interruption factor I wish to avoid.
