Tonight Jason and I ran into Lowe's (the hardware store, not the grocery store - I didn't need an ice cream fix tonight... I actually still have some in my freezer, thank you very much) to get a piece for our hot water tank. As Jason was handling the purchasing of the item at the self-checkout, I was trying to cover Satanic Sally's boisterous "mouth." At the top of the machine I saw what looked like speaker holes, so I placed my hands over said holes to see if it would at least muffle the sound. Yeah, not so much. I swear, there are hidden surround sound speakers all over that machine. I think the machine even got louder, as if saying "Ha! Trying to shut me up? I don't think so, missy."
So, note to self - don't trust a self-checkout machine with you secrets. She won't keep them.
