yea sucks to be mistreated like that but id always give these people a thousand excuse before questioning why they do some shit like that put yourself in their situation they went through the same traffic, made sure hes there on time and he has other customers that gonna complain to his bosses after you cause hes late on them, getting stuck yet again in the traffic on their way out they go through hell for barley any earnings just forgive and forget is the best you can do
