Spaced!!!

Was wondering if anyone has ever gone shopping.  Coupons in hand, and never gave them to the cashier.  Your mind is somewhere else and you just space on what you are really there to do? I did that today. Realized after I cashed out i forgot to give the coupons.  I really wish all stores were required to ask if you have coupons for days like this.  Thank goodness the service desk ladies were friendly and let me use my coupons.  Just had to hand the receipt and show them the item it matched to.  Today really wasn't my day to go shopping LOL.
