Ms Tongbram pays the women $80 a month.

Having graduated from university in the United States last April, Fearnley was ranked outside of the world's top 500 just 12 months ago.Since then he has made one of the fastest climbs in ATP Tour history and broke new ground at the Grand Slam tournaments.

The eye-catching draws continued when he was paired against Swiss former champion Stan Wawrinka last week at Roland Garros.The manner in which he quietened the pro-Wawrinka crowd in an efficient victory stood him in good stead for facing Humbert.Fearnley, whose background in the trash-talking US college game helps ensure he does not get fazed, sapped some energy from the home fans in a confident start.

He did trail by a break in the second set, but ultimately progressed in the way which no player wishes to win.Humbert tumbled as he stretched for a return at 40-40 in the eighth game and clutched his right leg.

After receiving treatment, he tried to continue wearing heavy strapping and lost serve before deciding it would not be sensible to carry on.

As a result, Fearnley - now 55th in the world - moved into the last 32 on his French Open debut."We have recently installed a new system at some stores which helps customers using self-service checkouts identify if an item has not been scanned properly, making the checkout process quicker and easier," a Tesco spokesperson said.

The supermarket did not say which stores or how many stores the new system was in.If an item fails to scan, customers are shown a video on the self-service screen of their attempt, accompanied by a message saying: "The last item wasn't scanned properly. Remove from bagging area and try again."

It follows a similar move by Sainsbury's, which has rolled out AI recognition technology at self-service checkouts at some of its stores."We regularly review the security measures in our stores and our decisions to implement them are based on a range of factors, including offering our customers a smooth checkout experience," said a Sainsbury's spokesperson.
