I'm sorry, if I'm buying a $4k machine the last thing I want to see is a tip % option. I'm all for them to make more money and have better conditions but no way this crap.

Apple’s Unionized Store Wants to Start Accepting Tips from Customers

Workers at Apple Inc.’s unionized store in Maryland are asking for higher pay and additional time off, along with changes that could affect the company’s tightly controlled retail experience, such as letting customers tip employees.

@paul as a former store employee I was offered tips all the time. Not on purchases. On the hours of free support we gave out. It wasn’t something we asked for but when you spend ten minutes helping someone solve their problems, oftentimes they want to pay you. Weird huh?

@paul 90% of our days we’re generally spent answering questions and showing people how to use the tools they’d already purchased. Most brands charge for that. We did it for free. I would say if the questions I answered I was offered a tip about 40% of the time. $5. $10. $20.

The Apple Store model is extremely generous with time and support. Some folks appreciate that.
