It's bizarre that the Waitress gave me the option of paying through her instead of using an app. So why the app? The Waitress is already serving, I am paying for the service charge.. I guess it is for those who don't want to wait and just want to pay quickly (with extra) and leave.

The same customer service person also asked if the first letter of my email address is in upper or lower case. Trivial innocent question but it made me think about naming and digital identities again...
