Don't tip coffee into the bin
Beckwith says a lot of customers tip hot drinks in to the bin, a move that makes for a huge clean up job.
"The trash bags are already disgusting when we get around to changing them, and dumping liquid in them just makes it worse," he told The Sun.
Talking on your phone or texting
Not only is it incredibly rude to be on your phone while placing your order, Beckwith says it also makes it harder because customers aren't able to concentrate on listening to the questions baristas are asking them.
He suggests keeping off your phone when placing your order, to make sure you get the coffee you want.
Pick your size wisely
Beckwith says when placing an order, "probably about a third of all customers" don't specify the size they want.
If you don't know the name of the size, it's better at least say big or small, he advises.
Baristas aren't mind readers
Many people expect their barista to know what they want, even if they don't say it.
Beckwith has heard time and again customers say things like "I didn't want cream" or "I wanted that iced", but never actually made these requests when placing their orders.
It's better to give more information than needed at the start, in order to make things easier for yourself and your barista. As Beckwith puts it: "We are baristas, not psychics."
