Just say "no."

I just hate it that every time I go to check out at a store the first thing that the cashier does is ask for my phone number. Like a robot, I have always given it out in the past. No more! I don't care if they do send me exciting deals or rewards, if they don't divulge the requirements for those rewards beforehand I do not see any reason to give them my phone number. It is a waste of time and an invasion of privacy. I started this refusal when I went to the maternity store about 5 or 6 months ago to get some breastfeeding supplies for my baby who just happened to be with me and screaming her head off because she was ready to go and eat. They were actually asking for my address and I really didnt have time to remember which one they had on file (since I had recently moved) and spell it out for them, etc. I just wanted to buy my stuff and leave. And after much hassle, I did just that. Ever since then I refuse to give out my phone number or address. When they say "Can I have your phone number?" I just say a flat "no." They normally just say, "okay" (after a weird moment of shock on their behalf). Surely I am not the only one who doesnt give it. Does everyone just give it up like that, like I USED TO do? If you are reading this (actually I doubt anyone reads my blog, its just a place for me to vent and practice my writing skills) I dare you to just say "no."
