Starbucks
When ordering a frappuccino at Starbucks don't order by the promotional name, think like a barista and order its components. For example, next time you want a raspberry mocha frappuccino order a "mocha frappuccino with a shot of raspberry." You will get the same drink 10-20% cheaper.

If there is a long line to go to the bathroom in Starbucks, the baristas sometimes cut the line if they need to use the bathroom by grabbing the broom and announcing to everyone on the line that they need to clean it.
The next time a barista does this to you, call them on it.
Welcome to Starbucks, may I please take your order? Yes, I'll have an iced doppio in a venti cup please. Sure, that'll be $x.xx. Now take your iced doppio to the coffee bar and get all the free milk you need to make that iced latte or cappuccino. You just saved $2+ that you can use for tomorrow's coffee break. Can you say twofer?
