A Simple Question

Dear Miss Manners,

My husband and I are having guests over for dinner this weekend, and there’s a point of etiquette where we can’t seem to agree. I say each person should pay for their cocktails and wine when they order them. But he says one should discretely present them with a bill for their totals, along with the price of their meals, at the end of the evening.

And how much of a tip should we, as good hosts, expect? I know 18% is customary these days, but that sounds a bit low considering just what a nice place to visit our new home is.

Please respond quickly — it’s almost Saturday already!
