Prodding the assistance button on a flight could on the face of things be a harmless move, given that cabin crew members are aboard the airplane to help you should you have any requests or queries.
While most will avoid pressing the button altogether, opting to speak with an attendant as and when they stroll down the aisle, there's nothing wrong will grabbing their attention via the feature throughout your journey.
Or is there?

The Mirror reports that one flight attendant has revealed the times during your flight that you should never press the call button as it drives staff 'bonkers'. While they are there to help, calling at certain points could actually be dangerous to yourself and the flight staff.
TikToker @katkamalani even went as far as to say the flight attendants won't even come and help you if you switch the light during this time. She said: "It drives flight attendants bonkers when you hit your flight attendant button if we are on the tarmac or if we're going up or down on the aircraft."
This might seem a bit strange but Kat, explained: "The reason being it's a huge safety issue for us, we could get injured and same with you guys. So if we're on the tarmac, you hit this and it's not some kind of emergency we're going straight back to our seat."
So on the tarmac you may get a response but she added: "If you hit this while we're going up on the aircraft or we're going down landing, we won't even come to the light we'll come to it afterwards. But don't hit this button if you need a barf bag or a blanket, water, headphones, food, any of that stuff because your flight attendant won't be so happy."
One passenger confirmed Kat's warning and wrote: "Had to hit the help button on the tarmac once. The attendants ignored it two times, but my mom was having a heart attack. After the third time they came over to tell me to stop pushing it.
"Then they saw what was happening. A truck picked us up from the plane so we could get medical help."
Commenters were quick to defend passengers who may not know any better, with one saying: "I thought they would just come whenever they thought it was ok. I didn't know they would hold a grudge on it."
Others questioned why the attendants didn't 'announce this to us at the beginning of the flight before we move' with the safety demonstration. Another quipped: "A barf bag is kinda good to have, no? Consider the alternative....which is cleaning it up once the light is out."
