Average Service: $1 p/drink (for a latte/cappuccino)
"I think $1 is generous. You have to take that job [a barista] with humility. I think it's fair. It's also important for the barista to try and acknowledge the tip and thank them [the customer]. It's important to acknowledge, even if they give you change."
If you order a cup of tea: Anything is appreciated
"It's less work, especially if you're in a nice coffee shop. There's so much work in an espresso program. I feel like a cup of tea is certainly less work. A lot of places where I've worked will actually prepare a whole pot, but a lot of people still tip $1. I think $1 is great for anything."
If you order a drip coffee: Anything is appreciated
"A lot of people still tip $1. Some people will give us whatever change is leftover, and that's pretty fair too. If you tip as much as $1, you're being generous."
If you want to become a regular: $5 straight into the tip jar
"$1 a drink, or if someone put $5 in the tip jar, you'd certainly try to be a lot friendlier to them – it's weird the way that works. You'll learn those people's drinks pretty quickly, and that'll turn into a situation where if they're standing in line, and you have a free moment, you make their cappuccino and you'll bump them ahead of other people. [Five dollars] is a really gracious tip for a barista. I've been a barista for 15 years. Tips are 35-50% of a barista's salary. It's a lot. If you're making $8 an hour, it's not unheard of to still pull $12-14 an hour in tips. It's a huge percent of your income. You have to be friendlier to people who are friendly to you.
