Quick Ice-Water from the Bar -- Tip?
I often accompany my dad and his wife to nice restaurants -- they are near 80 and she moves particularly slowly. I am also treated to good places by my mom and her companion. Last week I waited for my niece at the bar.
Upon entering, I often beeline to the bar and ask for "your largest glass, filled with ice and then water." I then follow my dining hosts to the table.
Do I need to tip the bartenders?
