Here’s my rule for tipping...
If you order from a menu-—tip.
If you order from a menu board, even if they bring the food to you when it’s ready-—no tip.
Here’s my rule for tipping...
if I’m going to sit somewhere and eat/drink, and some one else will be expected to clean up after, i tip.
But even if I sit and eat and then bus my own table, no tip.
