Assume you frequent a particular bar. You know both of the owners and their wives/partners. In early evenings, one owner or the other will tend bar, but when it starts to get busier, one of the wives/partners of an owner takes over the bar.
Now, my understanding is that you don’t tip an owner…they’re getting their share of the profit anyway. But the question is, do you tip an owner’s wife/partner if they’re bartending?
My personal belief has been no…as a wife/partner of one of the owners, they are also sharing in the profit. So is there an accepted etiquette involved in this situation?
