James also revealed that if a flight attendant dislikes a passenger, they tend to use a go-to line.
"If a flight attendant ever says to you 'I will be right back' we don't like you... and then we just forget," James said.
Tired of being constantly bothered when he was trying to eat, James found a crafty way to make sure he could enjoy his lunch in peace.
"I have a trick – every time I wanted to go from one end of the plane to the other to eat my lunch someone would always ask me something," James said.
"I'm just like 'I just want to eat my lunch' so I used to put a can of Coke in a sick bag, put a rubber glove on and then walk through the cabin so it looked like I was holding vomit – no one asked me for a thing."
James also confessed to a naughty moment where he picked food off others' plates in order to make sure he was fed.
"We were going to run out [of gnocchi] so I had one of lots of them. I took one from everyone's plate to make my own bowl," James admitted.
As for getting upgraded, James stated that kindness gets passengers much further than any other tactic.
"It's really simple it's not hard. Hundreds of people come past us and shove their boarding passes in our faces.
"If you go 'How are you, are you having a good morning?' we remember you. 98 per cent of people don't, they don't care. They're on their phone."
