I wonder if the intent or hidden upside behind a policy like this would be incentivizing people to stop taking 'under the counter' cash tips and move them to be registered income / by credit card. To be clear, it seems like most tips have moved to CC already (at least in the areas I find myself in), but if there were any regions where cash tips are still used to hide from taxation, this could be a nudge to do less of that? I'm definitely dubious of the impact of anything like that, just a thought that came to mind when I saw this.
