3 and 1/3!
People can be very particular about their Starbucks drinks. Not only do you have to prepare their drink in a certain cup size, but you also have to use the right coffee, the right amount of milk, prepare it at the right temperature, and add just enough pumps of a sweetener to fully satisfy your customers. Basically, it all translates to more work for the baristas.
This employee shared their experience about a lady who had a very specific order. She asks for 3-1/3 pumps of vanilla. 3-1/3. 3.333 (indefinitely) pumps of vanilla syrup. Can she taste the one-third pump? Probably not.
