Do you tip more if the food is good?
Do you tip more if you buy a fancier bottle of wine?
Do you tip more if the bartender or the server comps you on an item?
When you split the check, do you look to see how you tipped relative to your friend?
And do you tip more if the server recovers from an error that someone else in the restaurant made?
I hope it’s clear that we’re all irrational. That this isn’t really about tipping. And that tipping is inherently an inefficient and unfair way to compensate people… We shouldn’t make everything rational, but we should be careful that we’re achieving what we set out to achieve.
