I know that some American tourists actually do this, on giving servers cash tips as if they’re underpaid by their employer (since they’re used to it in the USA along with growing up with that mindset) but overlook the fact that servers are paid the minimum wage in the EU, as it’s not “typically” the norm. This practice is being exported it seems, in another region where that isn’t common.
Whatever usefulness it might theoretically have, forcing customers to pay employees’ salaries has generally been an exploitative disaster in the States, and just one more feature of late-stage capitalism. Sure, it’s always possible to find some outlier jobs in which one can indeed make good coin from a tip system, but the point is that such cases are the outliers.
