I agree.  I do this with the caveat that I will call out somebody who shirks who can bloody well afford to pay.<p>Ever since grad school, we&#x27;ve always had a gradient of people from affording to eat out to not really being able to.  As the generous folks covered me when I was poor, I&#x27;m happy to return the favor now that I&#x27;m not.<p><i>However</i>, I&#x27;ll generally make a spot check on someone who can really afford it but didn&#x27;t seem to put in the right amount.  If they don&#x27;t pay enough <i>for themselves</i>, I&#x27;ll give a quiet gentle reminder (&quot;Hey, remember you did eat part of those nachos and had an extra beer.  You might want to recalculate your portion.&quot;) and that generally solves the problem.  Most people generally just forget as it&#x27;s pretty easy to miscount in a shared context.  And, if this is the first time and they drag their feet, I&#x27;ll just pay it and talk to them afterwards.  They may have hit a rough patch in life.<p>However, if the group gets to 15-20 people, I occasionally get someone who just systematically shorts things <i>every time</i> who is making more than enough to pay their share.  If it&#x27;s the third time it happens, I&#x27;m whipping out a calculator and calculating their portion <i>exactly and publicly</i>.<p>At that point, they either shape up when I&#x27;m around or they never show up again.  Either solution is fine by me.
