Long Timer

I have worked as a driver full time for many years and for the most part I like this job.. I love driving, listening to music n podcast. But every once in a while this job just keeps dumping on you. Yesterday I worked from 10-6 and made $12 in tips (which is the lowest I've made in a full day) and $26 total with mileage.. today my first delivery was a $200 order to an animal hospital and they stiffed me. Some times I just wanna rage quit but I know I need a new job first.. thanks for letting me vent!
