It is absolutely justified. Businesses are able to pay employees, it’s just more profitable to move that burden onto customers.

Result? Customers pay more, and workers don’t have a stable income. The only winning party is a business.

By tipping, you help the worker short-term, but aid in proliferating a system that makes it so much worse for them.

That’s why I love cultures where tipping isn’t just uncommon, but is flat out rejected, because workers are paid well and are proud of it.
