I had a dispute with a Jewel-Osco on Western Ave in Chicago and did this for months after work. Fill cart and then leave it in an aisle out of sight of the security cameras. Cashier had given me some lip over something, can't recall what. I was determined to cost them money in shrink and labor for the "put backs."If this happens then 60 or 70 ODT members go in one on a Saturday and each fills a cart. We all go in line and it when it won't let you check out because you don't subscribe. Tell F-Off I ain't subscribing and leave the cart there. From there we all drive to another one and do this every Saturday until they rescind the practice. Those retired members can group up during the week. Keep doing it just for ****s and giggles.
Be sure to get products like meat and dairy, ice cream. you know, very perishable stuff. cut lunch meats and cheeses from the deli.
Treat foolishness with foolishness.
