Ignore Louis at your peril.
There are fewer things that are more cringy in life than putting your hand out for a handshake, only to be left hanging. This indignation happened to Manchester United boss Louis Van Gaal on their tour of the US.
Take a look as he arrives for an interview with MUTV and puts out his hand to the presenter Stewart Gardner.
Gardner doesn’t see it and Louis takes swift action. He’s a stickler for manners is Louis.
Woops! #MUTV presenter in handshake fail with Louis van Gaal… #MUtour https://t.co/Z7YKfzu5Ud
