I have a Stratux , but would not want to rely on any GPS in it . My wifi only iPad loses wifi connectivity to it with irritating regularity . I use an external Dual XGPS 160 , which has been rock solid in reliability . Yup , just slap it on the dash and it just works . <| sep |> since customers are not obliged to pay it , what if they just stop doing it ? There would be no way to organize everybody in America just not tipping anymore . Most people don ' t want to be assholes , so they ' re not going to stiff their server just in case everybody else decided not to , too , which would never happen . A better approach would be to boycott restaurants that have tipping policies , that way you aren ' t having people work for you and then you refuse to compensate them as the system currently works . they might have to raise the listed prices instead of playing the peoples conscience to make this kind of donation . This is actually why I don ' t get why so many people are passionately against the tipping system . You don ' t want to pay 15 % more for your meal ? Well , if tipping didn ' t exist , your food would just cost 15 % more so it would be the exact same thing . The only difference is that in a tipping society , you can refuse to pay the tip if your server is shitty .
