ELI5 Why restaurants do not like to split bills for tables.

Why don't restaurants like to split bills for tables? Is it a POS thing? Something else?

Because it can be a ton more work. If it's 3 people on a slow afternoon, no problem. When it's a table of 20 on a busy Friday night, the extra minutes spent splitting up a check can take a toll down the line because it takes you away from your other tables. A good idea is to tell the server before you order that you will be splitting the check. That way they can go ahead and enter them into the system ahead of time.
