Yes, the proportionality is one stupid thing about tipping. If I take a super expensive bottle of wine, is the service worth more? Conversely, if I take the cheapest salad, is it worth less?
You mean I shouldn't have tipped the miminum wage South Asian who installed my beach umbrella? They're far from their family doing a job in a very foreign country, sleeping who knows where along with who knows how many colleagues and sending most of their income home.
