Based on the number of tipping questions/threads/confusions/concerns/complaints on this thread, it seems many of you share my sentiment; there really should be a great app out there to help guide tipping behavior, particularly at places new to you or in new or foreign locales.
1) Do you use a tipping app? If so, which one? What do you like about it, and what do you feel it doesn't do so well?
2) What is your relationship to the food industry? Diner, server, bartender, chef, cook, restauranteur, something else, some combination?
3) If you could design your own ideal tipping app, how would it work and what features would it have?
