McDonald's

The technology developed by Israeli start-up Dynamic Yield can automatically change menus depending on the weather, time of day and traffic.

McDonald's is reported to be paying $300m (£227m) for the tech firm.

Number-plate recognition would also allow it to offer customers at drive-throughs their usual food order, McDonald's told Wired.

The Szechuan sauce, which was only made in 1998 to promote the film Mulan, has become well known after featuring in the popular cartoon Rick and Morty.

In July the chain sent a large bottle of the sauce to the show's creators.

They then announced it would come back for one day on 7 October, but fans were left disappointed after stores ran out.

In one video, police can be seen holding back people chanting "we want sauce".

Officers also attended other stores because hundreds of people turned up.

Earlier this year McDonald's (MCD) responded by putting filters in place at most of its U.S. restaurants, a change that was disclosed this week. The company had already had the filtering in place at its U.K. restaurants.

The major sponsors each issued statements saying Blatter should quit after Swiss criminal proceedings were opened against him last week.

Coca-Cola took the first step, saying: "Every day that passes FIFA's image and reputation continues to tarnish."

McDonald's said Blatter going would be "in the best interest of the game".

The 79-year-old is accused by Swiss prosecutors of signing a contract that was "unfavourable to Fifa" and making a "disloyal payment" to UEFA president Michel Platini but denies any wrongdoing.
