When you go to a bakery in England in the afternoon, and you are not a familiar customer, how does the salesperson greet you, and how do they ask what you would like?
“Good afternoon, sir. How may I help you?” seems overly formal, but “Hello. What would you like?” doesn't seem ‘English’ to me, either.
What is a common way for a salesclerk in a shop where things are sold over a counter (such as a bakery) in England to welcome a customer and ask for their whishes?
