I refuse to give information to stores when they ask, and when they tell me it is required, I just still say NO.

I have been told many times it is for my protection and then I ask they to explain how. I have even had my grocery store card revoked once they realized that my address of:
1 Any Street
EveryTown USA, 12345
Phone 555-1212
Were not real they revoked my card. I in turn stopped shopping there completely.
In summary I do not see how this program is going to make me safer or the lines shorter and even though I am in Airports multiple times per week I am not going to participate.
All for now keep your comments coming.
