My favorite guest presented a Bed,Bath & Beyond 20% off coupon for her groceries, stating that Target now accepts competitors' coupons. I explained that I could only accept Target and/or manufacturer's coupons and she got pissy with me. The guest behind her asked, with a big grin on her face, "When did BBB start selling groceries? Give it up, lady. You're not getting 20% off your grocery bill."
She snatched up her 20% coupon and stormed off, with everyone in line laughing at her.
Then yesterday, I had a guest insist that her item was on sale for $5.49 (it was a $14.99 product) because "That's what the sign said." I had time, so I walked back with her to find the sign that had a completely different description on it (saline nose spray instead of cold medicine) and a team member standing there putting the sign on the corrent item, who said, "I watched you move the sign, ma'am."
Funny stuff.
