1/ Random payment trivia: the reason restaurants have two receipts, one with the items you got and a second one with the total amount + signature, is that in the early days of Visa they were worried that restaurants wouldn't sign up...
2/ ...because they'd worry their competitors across the street would know what the most popular dishes were if they could see the line items on all the carbon copies.
It's been 50 years and we still split the messaging into itemized receipts and payment details. 🤦♂️
