I agree with you.  When I check into a motel they ask me if I am an AARP member. I say no, why ?  They said they could give me a discount if I was a member.  I move a little close and look them staight in eye and say, " You mean you are going to discriminate against me becaue I am not a member of AARP?"  90% of the time they are speechless.  I did even get the AARP price when I said that. lol. 

Give it a try sometime.
