If I’m eating out at a bar by myself, it means I don’t have to lose my table to get up and order. I also have social anxiety, if the bar is packed it’s a real problem for me. I’ll usually end up hovering while everyone else takes advantage and pushes in front of me.

The Wetherspoons app in the UK is a great example. Easy and fast to use, requires no account/PII just pay with Apple Pay.
