Tipping threads on GT are always fun. But, they always beg the question....when/why? Why does the guy filling the growler get tipped for merely adding liquid to a jug and may be the manager making a nice salary, but I never see anyone tip the guy behind the meat slicer/meat counter/fish counter. I have also never noticed anyone ask, hey do you make minimum wage? Should I tip you? They guy boning and filleting fish is doing more work and much more specialized work in relation to filling a jug, not to mention all the carp he has to clean up...note that this is just a random example to get the conversation started. So, what specific set of circumstances in your mind, justifies/mandates you leaving a tip? Or, is it merely fear of cheapskatery? Are you "lording," as is popular to assert here on GT? What drives some to have such anger towards others' choices they make with their own money? What say you?
