From Sam's Clubs membership terms ..
Receipts: To ensure that you are charged correctly for the merchandise you have selected, you will be requested to show your receipt when exiting.
Sam’s Club reserves the right to inspect any container, backpack, briefcase and so forth upon entering or leaving the Club and to refuse entry to anyone at our discretion.
Seems as if they cannot force you to show a receipt .. says REQUESTED ... indicating optional
Seems like they can demand to inspect .. but failure to do so can only result in them refusing entry only.
So, no, they cannot force either when you are exiting.
Do shrills make you comply with their request? Seems like a good place to train!
"Hey hey hey, show me your receipt !!"
I've had stores do this...I just brush their requests aside and continue my travels. Threats don't affect me as long as they are not illegal threats.
I recall in boot camp we did guard duty ... the Sgt told us not to allow entry into the bldg w/o the person showing ID. Well, the SGT came to the door one night and asked to be let in ... the guy on guard duty refused w/o a showing of ID ... SGT screamed and yelled and guy let him in w/o showing ID ... then he got the **** kicked out of him by the SGT for letting him in w/o ID. Funniest chit. Boot camp was the funnest of all. A million hilarious stories. This is just one. The movie Full Metal Jacket reminded me of boot camp....the only movie that every really caught the experience even close to reality. Nowadays, the instructors can't hit ya ... so I'm told....
So yelling, threatening, screaming, whining, crying, pleading, etc. have no effect on my behavior. You can do all to me and I'll just sit there with a chit eaten grin holding back the laughter. Ahh..good times.
