I just strongly avoid using any business that deals with tipping. This way I don't worry about tipping calculus. In the case that I do engage with such a business, I only tip when there is objectively individual work being done: Eating out at a table? Tip the waiter 15%. Waiter was extremely rude? Tip the waiter 0%. Picking up food at a counter after ordering online? Tip 0%. Bringing bags into a hotel? Refuse help so I don't have to tip. I really wish tipped workers would just get paid an honest wage to begin with, meaning the true cost of labor would be baked into product prices!
