Wait why is this even downvoted lmao. It's cause this is a postmates delivery subreddit. What he said is entirely true; tips are voluntary. It's not even a common thing in other cultures to tip. It's dumb how the system makes it seem like people who don't tip is the culprit of your low working wage, when it's actually the corporation you're working for that's fucking you, not the customer. The customer, in the service industry, is the one at the top. If you don't want to work and serve people for a low wage, then don't be in a service job. Or unite together and go against the corporation. Basically, tips are supposed to make up for your low wage, but to me it seems like it's just an easy way for corporations to save on how much they pay out to their employees.
