People will use Venmo for anything but splitting a bill. It's fucking wild. We regularly have parties of up to 80 people in our restaurant, and they just can't seem to understand that 80 different checks is a nightmare for the waitstaff, let alone the kitchen and the bar. They will fight tooth and nail to not have combined checks.
Edit: Guess I should have specified that these are reservations that we communicate with before hand. Typically office parties and corporate events or large weddings. You know, things that would typically go on a single tab. I don't think anyone here appreciates how long it takes to take individual orders for 80 people. Even at 30 seconds an order, thats half an hour of order taking, not to mention the time it takes to input it. Then you have special requests and questions about ingredients. It's a lot of effort to split that up.
