Dave, yes you are correct. I only have one screaming rug rat, unless you count my wife… (JOKE!)Kevin,
To fit in the checkout line better, bury your phone in the bottom of your purse and don't even think about using it till it's time to pay. Then you fumble around in there a bit, take time to tell one of your screaming rug rats not to jump out of the cart. Finally finding it, then discovering it doesn't work very well powered off. Trust me , some humans will find a way to screw up the simplest things, oblivious to the suffering they cause.
As I said " strangling them in my mind"...........
My wife did have to show me how to use it. The first time I tried, I had a mask on. And of course the credit card app on the phone needs facial ID, so I couldn’t get it to work. It took some time, a long time. My daughter was with me. She never said it was the mask until we were outside. I’m sure she was thoroughly embarrassed. Oh well.
