It just happened if you ask me at Wal-Mart (Supercenter shop #1279, 10411 N Freeway 45, Houston, TX 77037) a month ago. I purchased a whole lot of material, over $150, & We glanced inside my receipt whilst the cashier ended up being handing me personally the bags. We saw a cash-back of $40. She was told by me i didnвЂ™t request a cash right back & to delete it. She stated IвЂ™d need to use the $40 because she couldnвЂ™t delete it. She was told by me to phone a supervisor. Supervisor came & stated IвЂ™d have to just take it. We stated NO! Taking the $40 would be a cash advance against my Discover & We was interest that is nвЂ™t paying a cash advance. Then they would have to delete the whole order if they couldnвЂ™t delete it. Therefore the supervisor had the cashier delete the order that is whole re-scan every thing! The time that is second looked over the electronic pad before we finalized & a cash-back of $20 popped up.
