Andy Murray has been working on his service - but not in the usual way.
The new world No.2, in Ohio for the Cincinnati Masters, decided to play a prank on some unsuspecting locals.
Pulling on a wig, hat and glasses, Murray dished up ice cream to the public at a branch of the famed Graeter's emporium.
When @andy_murray is disguised and serves ice cream for you then takes off his wig to take a pic with you 😍😍😍 pic.twitter.com/w4qGZXqEz0

Twitter user Julie Boniface then posed for a selfie with the Scot, once he had revealed his true identity.
A spokesman for Murray said: "Andy is in Cincinnati for the tournament and was just larking about in disguise to see if people could recognise him."
Anyone ever said you look like @andy_murray? This @CincyTennis ice cream server looks a LOT like #ATP World No. 2! pic.twitter.com/79od3pcfKu
— ATP World Tour (@ATPWorldTour) August 18, 2015Murray certainly deserves to blow off some steam, after ending an eight-match losing streak to Novak Djokovic on Sunday.
Not since his Wimbledon triumph 25 months ago had Murray beaten the world No.1, until a 6-4, 4-6, 6-3 victory that saw him lift the Rogers Cup in Montreal.
The US Open is set to get underway at the end of the month, and Murray is feeling confident ahead of this week's tournament, where he faces Mardy Fish in the second round.
"I feel good. The last couple of matches I felt like I played very well," said Murray.
"It is quite different conditions here so it will take a few days to get used to them and hopefully I can try to get through my first match somehow and hopefully start to feel better as the week goes on.
"But obviously last week was great for me regardless of how I play here and was a good win for my confidence."
