That&#x27;s not usually the waiter&#x27;s fault. POS systems are, generally, a POS. Sure, they should have some way to split bills, but &quot;should&quot; does not always mean &quot;does&quot;. Or maybe splitting the bill requires spending a few minutes manually building 2 new checks, which may not be something the waiter has time to do in a busy restaurant. Or maybe the waiter would be happy to do it but the restaurant itself has a policy against splitting checks (or at least, splitting checks for parties under a given size; I&#x27;ve definitely been to places that allow you to use 2 credit cards if you have 6 or more people, and never more than 2 cards).
